One of the best videos I’ve listened to.To the point and real
I don't understand how you don't have more subscribers ! Awesome video, I've got an 06 LBZ, but love em all.
Joshua Dansie Thank you I appreciate that man! I have technically had the channel for a year or 2 but I just started actively sharing content a few months ago so I'm just starting out. I just love working on these trucks and talking about them so this is my outlet!
Love these types of videos bro, I got an LB7 Build myself and found this very interesting, keep up the good Duramax content. Perhaps we can collab one of these days
Boost And Redline Thank you sir! Youve got a pretty sweet build going on! We definitely should some time, this ones not the prettiest but Im hoping to start helping that out here this winter
little late in commenting but i agree %100 with everything you just said, great video! i have a 2003 lb7 pushing 650 daily driven great trucks but expensive too build lol
My first things were head gasket, studs went to sac 90, airdog,cp3, turbo, full cooling system meaning pipes ,radiator intercooler water pump and so on. Now I got trans done and just put efi live on it. Haven't done a done in a while but she definitely hauls ass. There's alot of other things I've done but I feel like those were the most beneficial ones
You’re 100% spot on with Everything you said so don’t worry about the haters
Beautiful blackout!
Liked this video. I got an 02 LB7 300,00 miles on it. I bought new. I up graded the intake with a larger turbo cone and 4 inch diamond eye exhaust. Nothing else it takes boat anywhere i want anytime. The only problem i had was O ring at fuel filter leaked. No real problem in 23 years.
Beautiful truck 👍🏻
Thanks for the info!!
You had me at trans upgrades 😍!! So often, guys will do all these engines upgrades and completely forget about the fact that the trans needs to handle all that extra power! Sound advice man, you have my like/sub!! 👍🏼
Cheers man I appreciate it! You are totally right everyone wants to put their money into fun power and sound upgrades, but sadly, especially with the 5 speed Allison it doesn't take long and your staring the cost of a built trans right in the face.
I mean common sense really. Alot work goes into these but in the end its all worth it
For an Lb7 id say grade c head gaskets,arp studs,trans built, and then 5 position with efi live...preferably with cold air intake, and or some kind of exhaust mods prior to tuning.
You want the grade C head gaskets as well, especially on high milage motors... I learned the hard way...
I definitely can't argue with you there, this truck has them with ARP headstuds as well. Headgaskets are such a hit or miss thing on these trucks, and from what I understand its not really the headgaskets themselves that are the problem, its the OEM head bolts that stretch out of spec, allowing the gasket to fail. Even on the notorious LLYs it is so randomized. Some guys fail on stock power, some trucks never have an issue, even pushing 650 hp. Seems to be the luck of the draw more than anything else. My last duramax was an 05 LLY with 135k and I bought it unknowingly at the time with bad headgaskets (I was inexperienced and naive at the time haha) So I immediately got to drop a ton of money to make it solid again. So all in all I wouldn't say 100% that you need new gaskets and studs just right off the bat, but it is definitely something to watch for, and if your already doing new injectors on one of these LB7's if you can I would recommend digging a little further and replacing the gaskets, and oem bolts with ARP studs.

Thank you I appreciate that a lot! I love these trucks and talking about them, we can all learn something new from each other so thats why I make youtube videos!
Your LB7 sounds a lot like my own, just needs a built trans to help lay that power down reliably! Trans tuning is really nice I recently had mine done to get rid of the defueling between shifts and to be able to launch in second gear when sled pulling. Getting rid of the defuel makes for such a smooth driving experience I love it.
@@FixedVaneDuramax your welcome...since my trans is stock can..you recommend me leaving the trans alone..or what is your thought on having the defuel turned off? Pros,cons?
DuraMAxFanatic Sorry for the delayed response, the short answer is Im not sure. I think it would be totally fine for normal daily driving, as long as you’re not putting the wood to the truck constantly. I would maybe start to worry about it if you are competing, especially the 1-2 shift under high boost. These 5 speeds shift so weird anyways I would be uncomfortable with that personally.
@@FixedVaneDuramax ..its ok your good...i will just leave it alone ..until I get the trans built!
right now I would be happy to just get back to stock power ... have to baby the truck but I depend on it for field work.. got it from a yard and it turns out it was originally a utility truck for a major metro. IMHO they took all the questionable parts and put on it, then unloaded it. I know very little about diesels but am trying to learn as I go. hoping to put on a lift pump to help with the lack of power and unexpected stalls. starts good. sounds ok at idle. deleted resonator but never hear it spool up. will make a jig to test for leaks in boost side. only code I have is a bad intake heater. if u know of a good video for beginners with lb7 and how to test/monitor it would be appreciated.
Just bought a 02 crew cab. It’s a one owner truck with 160k only gave the man 13500 never used for work flawless truck…..getting her straight piped tomorrow
Where did you get your headlights and tail lights?
Can you make it to 550 to 600 without head studs and better head gasket?
I did all the performance mods without going too deep into my engine so intake, exhaust, tune, lift pump , boost increase valve and just sent it until my trans died 2 years after my first limp mode. Bought a PPE stage 5 kit with a billet cover and billet stator triple disc converter got it for around 3100 and had it built by a guy who worked at Allison for years and now owns his own shop in NY. Cost around 1300 dollars for labor, seals, and a sensor.
Next up on the list is suspension mods because I’ve never launched it at all.
Nicely done sir. If I was to recommend anything, get a decent set of HD tie rods, a set of Pitman and Idler arm supports, and thats really all you will need. If you want to spend $1500 on a whole new Kryptonite front end thats up to you but its not really necessary. Just make sure your lower your front end to ensure a decently straight angle on your CV axles.
is your truck in stock suspension?
did your mpg go down at those HP levels?
I’ve had bad injectors for 2 years now and nothing has changed truck runs strong as ever just smokes at idle. I really gotta do them though. I love LB7 content bro I actually posted my 5” before and after on my channel. Please keep up the good work I’ve seen all your videos I also changed my manifolds up pipes and downpipe on my own without snapping any bolts.👍👍 hit me back bro.
how do you know that its your injectors?
I have a 2004 LB7 with the MANUAL 6speed, it has a South Bend clutch with a rating of 450hp, I’m looking to achieve 400-425 wheel up, will my tranny hold up to this since it’s a Manual
I honestly have a cat eye with a lb7 that is my tow pig hardly anything is done to it but I’m here some how at 2 am when I should be sleeping
My LB7 went on limp mode. I was going 80 freeway it just rev the engine. Went to low gear. And it did not let me go on reverse. I had to park n started it
Its called limp mode do some research it happened to me too
My 2003 zf6 was tuned on a dyno with efilive. Probably a dozen passes till it was tweaked and tuned to where we wanted it. 500hp and 1100 fpt is where it is currently at. There's more I want to do but I don't abuse it.
F18M 223 There you go. I love these trucks for the fact that with not too much you can have a really fun to drive, reliable truck. Im pretty much at the same point as you. Dynoed at 511/972 last year, ive done some tweaking since then so Im hopefully to be more like 530-550/1100 at this point but who knows. Ive just now started sled pulling a little so I am staying with a stock charger, but ive got a few more things to play with yet to really max out the stock system. Guys say that 530hp is the max you can see from a stock charger but Im going to see how far I can stretch it while keeping good driveability.
@Zfdmax I also have a zf6 truck but mines a 04 lly, what clutch system are you running for 500hp
6:27 ik i’m a year late but...did ANYONE see peep the rabbit in his driveway?????
My Allison went out and I’ve been looking far and wide for a ZF6 to swap into it.
I thought allisons last forever
Estephanie Sandoval they do user about 600 hp but any stock trans will not hold a ton of power nor if you have super high mileage with little maintenance
Estephanie Sandoval they do when the truck is stock and maintained. I maintained mine but my truck isn’t stock so the extra power destroyed it.
dang, I got an lb7 to, 64mm stealth, fass 165, all new injectors, s&b intake, ppe fuel relief valve, mbrp down pipe, beans fuel sump, tune, and a intake horn. wondering how much hp I'm running? how much you think ill be pushing?? never dyno . oh and stock trans. lol let me know.. thanks. love the videos!!
HuntNreeL Impressive! Im similiar I just need to move past my stock charger yet. What are you running for tuning? A G1 stealth 64 from Dmaxtuner should add approx 80ish hp to a maxed out stock turbo-stock injector Lb7. If your stock trans with safe tuning, I would estimate 450 rwhp, maybe 800 lb-ft of torque. If you are untuned at all, maybe 400 hp. Max effort EFI live and a built trans would have you knocking on the door at 600hp all day long! As it sits, Im sure you already are, but be very aware of your power output when shifting between 4th and 5th gears, that will be your weak link in a stock 5 speed allison.
Fixed Vane Fun I have a super chip tune, no efilive yet, but dang , I gues I am running good power. Thanks for the info!! Keep up the good vids!
HuntNreeL You've got a great base for making decent horsepower! I need to get a different charger under the hood but I really want to get this truck dynoed again just to see if the slight turbo modifications Ive done actually made a difference. I really like the looks of Duramaxtuner's new G2 Stealth 64, but Im leaning toward the Fleece Cheetah 63mm purely because its in the same power area and honestly they just sound amazing with the s300 core. If you get your transmission built to hold it I would really recommend getting some quality EFI live tuning I think you will be amazed at the powerplant you have.
Fixed Vane Fun yeah hopefully done the road I'll get efi live, 63mm cheetah, yeah I heard lots of great reviews of them, they sound crazy.
Are you worried about the crank breaking when pushing 550 to 600hp on an lb7?? I got an 01 lb7 and did the boost valve only making 23lbs. PPE xelerator tuner, intake, 4in exhaust, PPE race fuel valve, hsp turbo horn, fass 100gph, xdp fuel filter delete.
Is it a possibility...sure maybe, but not likely. Realistically it would bend a rod well before it breaks the crank though I'm sure it has happened. Proper tuning keeps the low end torque at a safe level and many stock bottom ends are surviving in the 650-750 hp range for a long long time.
As far as your boost reading, how are you measuring it? If your reading it through your OBD-II port it will only read up to 22-23psi, thats as high as the oem sensor can go. If you want to read higher than that you will need either an EAS EGT Probe from your Edge CTS (if you have one) or a mechanical boost gauge.
Was wondering how hard does ur transmission shift into overdrive. I have same suncoast stage 5 kit and suncoast 1056 tourqe converter. And mine has all way s shifted hard into overdrive. Nice video man
Hey finally someone else running this converter! So mine acts pretty much the same way. It seems like it locks up harder the hotter the trans gets in my case. The owner of my local shop refers to Suncoast converters as "crank breakers" because of how hard they lock up lol hopefully thats not the case but yeah sometime it locks so hard I feel like it almost shakes the whole truck.
Yeah mines does the same the hotter the transmission is the harder it shifts my truck is 2005 lly this is what I have done to mine and lot of this was put on last few months air Rade cold air intake. Lbz mouthpiece banks aftercooler and piping. 165 fass lift pump , egr delete , up pipes. And down pipe 4 inch banks stright exaust , race fuel rail plug and both fuel rail fitting s been ported, dxp fuel filter delete, brand new bosh injector s , promaxx lbz heads, arp head studs , efi built tans tunes by ridge runner diesel, dp5 switch, edge monitor with egt probe, suncoast stage 5 with suncoast 1056 converter, transfer case pump rub kit. And brace. ,hevy duty transmission line kit, and deep pan, and I'm sure I'm forgetting something. And I'm thinking I have a oil leak ing in the pot side of the stock turbo been seen blue smoke last 2 weeks but clears up soon as start driving and will not smoke again until it sits and idles for a while. Going to pull down pipe and boost pipes Monday to see If I can find the leak. If it is. Going to get the 64 mm with 10 blade turbine. Turbo.
I have been looking at this turbo. ryansdieselservice.com/shop?olsPage=products%2Frds-64mm-045-10-performance-turbo
Jason Scruggs I love this, it sounds so much like my own old LLY, and its great that your pushing supporting mods along with actual hp gains for a well rounded truck. I dont know much about the garrett chargers those trucks have this sounds like a good excuse to upgrade if you can afford it. I dont know much about RDS but that seems like a good price and a decent charger, I would take a look at Danville Performances 68r as a comparison, the price might jump quite a bit Im not sure.
Cool I will let you know what I end up going with on the turbo. I'm thinking and from info I have found RDS 64mm is really close to same thing duramax tuner is doing with the stelth 64. If anyone knows more about this please let me know. Fixedvane I love ur sled pulling video and how u set up the truck to get ready for a pull.
I have a question I also have an LB7 and when I’m in it and I hit a bump I get a really bad shake and the trans just locks up in third gear and limits me to around 45-50mph does that mean I need to rebuild my trans
That does sound exactly like limp mode, is it sending codes as well? It would be on its way out, try to stay out of it in 4-5 gears and you can limp it along until you can get it rebuilt.
So if I did an 5 inch straight pipe,ppei efi live, and egr delete and wcfab air Intake. Would it be to much for stock trans?
No, thats a great place to be. Truck will sound good, be healthier without the EGR bringing that oily garbage back in, and you will have a great driving truck that you will enjoy 100% more than stock. However, even with Kory's stock trans safe tuning you can still beat a trans up if you mistreat it. Youll be in that 400-450 HP range I'd imagine, which is great but if your repeatedly doing long hard pulls at wide open throttle, the trans will get weak, especially between the 4-5 shift. But if you drive like a normal person, you will be totally fine and love the increased power and responsiveness of your vehicle. This is exactly what I had on my LLY that I owned a few years ago, Kory's tunes, 4" exhaust, WCFab EGR delete and an S&B intake.
Thanks for responding. You answered all my questions-thanks so much
Where did you get your cab lights and were they very hard to install or did they come with the truck
So these came on the truck but I have installed cab lights on 4 out of my 6 trucks I've owned. I always order mine through gorecon.com generally. These are the low pro version meant for 07.5+ trucks but they will work on these trucks as well, I put a set on my 04 without an issue. Cab lights in general are not a hard job, you just have to be willing to take drill to the top of your cab.
Take your time, measure out and center up your lights without drilling, then drill the holes and run the wires. You will need to pull down the front half of the headliner to be able to run the wiring from the lights to your fuse box and ground. I have done the old body style lights, dodge lights(5 singles), and these new body style ones, they are all the same process.
Measure and center your lights (measure several times before drilling!)
Drill holes for screws and wires
Pull down headliner to access bare cab roof steel
Run wiring harness (bought or make your own) from power/ground up to cab roof
Fish light wires through cab roof
Use a black silicon to help seal lights to roof as you use the screws to fasten the light down for all 3 lights.
Hook power and ground from each light to power and ground from your harness, reinstall your headliner.
Hope this helps
@@FixedVaneDuramax thanks a lot for the info. Is the 07.5+ plugin the same as 01-07 like to plug in the wires on the passenger side
Caleb Eadie I guess I’m not sure about that, I have always just made my own harness and wired them to the running light fuse. I believe Recon sells a harness that you can buy as well to make it a quicker install.
What’s the best way to delete the egr out of an Lb7?
J M T Show I can’t say Ive ever done an lb7 emissions equipped delete, they are more rare in general, Ive only ever deleted an lly and lbz trucks. But I found this quick write up on a forum, it should have the info you’re looking for assuming you have a Cali emissions truck. www.duramaxforum.com/forum/01-04-5-lb7-duramax-powertrain/424818-lb7-california-egr-delete.html#/topics/424818
How would I find the best local shop for EFILive tuning? Clearwater Fl
Cape Coral, Florida here... 05 lly ccsb 4x4 sunroof rust free Florida truck 289k miles.
Did you ever find what you are looking for? I'm always looking also..
Id look into ppei or calibrated power they both have hundreds of hours of dyno time with these trucks. Countless hours have been spent modifying timing tables and fuel quantities. Give them a look
@@GMCJay_lly nope. I have not found anyone near Tampa bay
Elite Diesel Plus in Cape Coral. They did my headgaskets and a bunch of other work. Been happy with them. Only bout 1.5hrs away i believe...
Fixed Vane I need to get ahold of you with some questions and possible advice on my 04 lb7. How can I contact you?
If you have Instagram you can direct message me there as @raberle_lb7 or if you have facebook you can message me there as well. If you look on my main channel page on a laptop links to both my facebook and instagram are in the main banner at the top. Thanks!
Is this with Stock LB7 injectors?
Thomas Iwachniuk I am running stock injectors on this truck yes. You’ll run out of air with a stock turbo before you run out of fuel with stock injectors.
Could I run a boost valve on a completely stock truck? Would it cause issues or would it be just fine? Please and thank you!
You can put one in no problem, there may be some small gain to be had. To truly wake the truck up good efi live based tuning is the best bet.
Fixed Vane Duramax ok I want to tune it but right now it’s all stock and I don’t have the money to build the tranny so would you still recommend I tune it? I also don’t have a lift pump on it
You definitely can still tune it on a stock trans. Almost every reputable tuning company sells a "trans safe" tuning package, usually with the highest tune 100-125hp over stock. However, you do have to have some self control. Just because they aren't huge huge tunes you can still wreck a transmission if you constantly beat on it. That being said, you can run a stock trans tuned truck almost indefinitely if you drive it normally and don't hot rod around racing every mustang in the county. You will have a much more responsive, easy and fun to drive truck.
Fixed Vane Duramax ok thank you for all the help!
@@masonmanske1798 agree with fix vane
Im bone stock 6inch lift on 35s
I was scetchy of the tune also.
I bit the bullet and went for efi live w dsp5 knob and tcm tune and an airdog lift pump.
Ill tell you what its a whole different truck now. Smoked a few dodge chargers by a few feet. You should see there faces when we come to a stop.
What kind of torque numbers are we talking about here?
Generically, 800-1000 ft-lbs for a stock fuel/air, built trans truck
When my po700 code goes off I get stuck in 4th
Limp mode. There are probably more codes but a basic scanner will just pick up the p0700 generic transmission issue code. The transmission is slipping under power and saving itself.
What city do you live in? I live in Illinois also and I am picking up my LB7 today and i would love to get a group together to cruise, take pics and give each other advice.
I'm from the Peoria area, about 15 miles southeast of peoria actually. Meet ups are always great! The truck community is an awesome group of guys I have met a ton of awesome friends through our common interest in diesels and performance.
I live near Rockford il lmk if your ever in the area fixed vein!! Nice looking truck
Farmer Hanna369 What you got going on September 22? Come down to Petersburg IL for the Fall Truck Brawl! Dirt drags, show and shine, sled pulling, and dyno itll be a blast!
Ill definitely keep that in mind but Harvest is a busy season at work
Farmer Hanna369 Yep Im an Ag Engineer and still involved in the family farming operation so I understand. Hoping to be done with the heaviest portion by then.
I have a 10 speed
I only gained 2psi with my increase valve. I’m sitting at 22psi
Tactical Camel how are you reading your boost? With a mechanical gauge or edge cts? The edge only mirrors off the trucks ecm, which is limited to 22 psi, so anything above that isn't shown.
Fixed Vane Fun oh really, I guess i need mechanical ones then.
Yeah so you have 2 options(that I know of.) You can either get gauges (either on the pillars or single) and run a boost line from your Ybridge or similar location. Or if you do not want to get big gauges you can actually get an add on sensor kit for your Edge CTS. Look up Edge EAS Pressure Sensor for your Edge CTS. Basically it adds an auxiliary pressure sensor onto your CTS so you can read accurate boost. You will still have to drill and tap somewhere like the Ybridge to thread in the sensor itself, but this is a cleaner look than full gauges. Depends what you are going for.
Fixed Vane Fun I’m going to get pillar gauges, mainly because it’s cleaner and i can have more gauges that way.
Big 3 should be lift pump, injectors, trans.
Stage 5 suncoast for 4500 WHERE
Awesome video man. I live in southern illinois. Maybe a meet and greet and so me advice or a hand on my build. Hit me back and maybe we can private message or email. Thanks again
Bigen2315 You bet. Im no expert, but I can definitely try and point you in a good direction! If your on instagram shoot me a message or on here!
Fixed Vane Fun I am on Instagram but don't get on much but I'm going to start using it more.
What year is your duramax
2001, front end swapped.
Thanks
PPE stage five trans is 2500$
Jamie Trippy Maybe for the parts themselves and a nice triple disk converter. But to have the trans dropped, built, and reinstalled by a quality shop will generally almost double the cost for labor. Average guy can’t do that himself, or at least shouldn’t.
Hell no.ppe is 6,000+ for a stg5
www.alligatorperformance.com/ppe-stage-5-transmission-kit-for-01-10-gm-6-6l-duramax than go to a shop that has done this upgrade and has done it before you can have your truck back that day. And cost under 1000 in labor.
With all the guys building their trucks for big horsepower, why is it that no one ever upgrades the air to air cooler?
Harold Barrows They do generally after a certain level. Generally the cooler itself can handle the job cooling wise, but aren’t built for higher boost pressures. Mishimoto makes a really nice option for a replacement. But really there is no reason (that I can see) to swap it out until your stock one actually fails.
Yeah goes on Facebook so you don’t need a lift pump truck already got a lift pump in the newer trucks no I don’t they went from a Bosch fuel pump to a Denzo fuel pump and then those are junk anything Denzo is junk
all i had to do is a tune and cold air intake and i get 747 ho
hp
Not to rain on your parade, but a stock injector/turbo lb7 with a built trans and good tuning will max out around 500-530hp to the wheels. The turbo itself is the limiting factor, with a quality drop in 64mm or 67mm charger you can push the stock injectors upwards of 600 rwhp.
Right….more like 474 there Pinocchio ho
I get stuck in 4th 😂
LB7 diffs aren't that strong either.
Lol. How are you figuring 500? Just guessing or did you dyno it. I've seen delete stock 700hp
No you haven’t, unless it was running nitrous. A healthy stock turbo will max out around 530 rwhp. That is well proven over 20 years and agreed upon by every performance/tuning company in the nation. This truck dyno’d 511/972 completely stock, 565/1162 with a port&polished turbo/stock fuel, plenty more after the s467/12mm cp3/ 65% injectors.
