What downpipe is that
Great video and info! How do you get that heat wrap wrapped around the pipe being so tight.
Good video , thanks. I decided to restore my dad's 2001 3500 . Was wondering if it's worth it. I want to keep stock horse power ..
Thanks for the info!
What all did u do on the exhaust system
HahHahahaha 90-100 horsepower over stock is all an Allison can handle don't tell my 2003 Sierra 280k miles tows between 3000+28000 lbs almost daily at about 500 hp it's all in that right foot my boy if you drive like a teenager on his way to get laid it won't take it but if you take care of it it will take care of you
It actually whistles now
cost me 11,000 for new bosch injectors and injector lines and power steering and brake leaks injectors alone were 3006 bucks
A question When I drive LB7 on the road, temperature of engine is fine with a truck camper on its bed and a jeep pulled behind. But I drive the truck with the same setup on uphill, the engine Temperature goes high. Sometimes, I have to stop to cool the engine off. I am planning to replace two thermostats soon because I had a similar experience with my jeep. Is that what you would recommend me to do? Mine is 2003 Duramax. It's mileage is 140,000. I replaced all the fuel injectors. There is no other issue with this truck other than driving uphill with a camper on its bed and a jeep pulled behind. Any recommendations to consider?
Efi live. Game changer
Ps. Yours isn't even broke in yet. Mileage wise
What size bolt should I buy???
Me after I installed an Air dog on me 03 Duramax and left the stock fuel filter housing on, I was 8 hours from home my fuel filter housing left me stranded for a few hours couldn't figure out why my truck wouldn't stay running for more than a few seconds later found out it had a hairline crack in it replaced it, not long after it started to leak as well so i just did away with it for good and not had a problem since then. Really you don't need to have 3 filters on your truck If you often change your filters, you shouldn't have problems like me I change mine every 15K miles
Have you noticed any improvement with cooler engine temps or EGTs?
How much did the efi live cost you?
What we’re the bolt sizes you went with instead of using the pointless hex bolts
I went ahead and used the stock ones except on the top you’ll need to use a boat with a smaller head
Can you do a video going wide open throttle
What lift you got on that
4inch rough country
How in the ever living hell did you get it around the wire harness?? I cannot get in underneath it to get a flush mount up
Which harness?
What’s ur wheel setup?
20x10 moto metal 962 with 35-12.5 Dick Cepek extreme countries
The transmission going on limp mode is not a problem its designed like that to save the engine or transmission from damage.
It’s a problem when racing
Did you have to drill and tap a port for the boost gauge on the cts or does it read it through the obd2?
It reads it through OBD2
How do you feel about the fuel pressure relief valve block off plug ? Been thinking about doing that, do you know of any issues with them ?
On the LLY is the fuel pressure relief valve blocker plug seems to work really good for prevents the fuel rail from limping because once that spring is activated it seems to limp easier
@@DutchCreekReplicas oh ok, what about the lb7 ?
As far as I know the plug came on trucks 2004.5 to 2010.
It sounds really nice
Which cat did you remove the front one or the back one?
Excellent call upgrading the stuffy stock turbo horn. Thanks for the LB7 content!
Is that single exhaust?
Yes
helpful video for us lb7 owners. thank you!
Is this stock headers with no cats and straight pipe?
1 cat
@@DutchCreekReplicas I just did a cat delete with straight pipes. It’s ridiculous
with the 4 inch lift and 35’s do you have any rubbing problems? because i’ve heard some people say they have and some people say they haven’t and i would like to know before buying the 35’s
So at full crank I did rub a little bit on the plastics but if you were to take a Dremel or grinder and just file them down a little bit you would fit perfect
At highways speeds in overdrive is it bad
Not really
Hey I have a 3500 lb7 and its like the turbo isn't doing anything cant find boost leaks
Just had to replace the hot side pipe due to a hole from rubbing on the power steering lines.
Yup, the power steering gearbox will rub a hole.
Will a 3 inch down pipe help with the heat
yes it does! I'd start with a 4 or 5 inch exhaust with a high flow muffler or straight pipe, that made a huge difference with my LB7. Come peep my channel if you want to hear what the 4" MBRP sounds like on a LB7.
I put my intake horn on and the cold air is k&n and it seems that my 2003 lb7 hazes a lot more
Have you checked you injector rates or ran a cleaner through?
Nice! Do you have a 4” or 5” exhaust on your truck? My truck is currently stock so I’m considering both upgrades (turbo horn & exhaust).
PhilsLB7 I have a 3 inch downpipe that goes to a 5 inch MBRP exhaust.
Dirty Money Garage Thank you!
And if you’re looking to increase your turbo size with keeping costs down check out Lincoln Diesel specialties they have a 64 mm super core turbo that only comes with the compressor side of it so you don’t have to pay for the exhaust housing right now it’s on sale for under $800 a couple of guys and I’ll run it and they have nothing but good words to say and you could still use your intake horn and I’ll start components
Why not just take the air conditioner pump and the thermostat housing off? You would have so much more room on top
Alexander Monslow Didn’t need to take it off just to get one bolt. Besides it’s the wiring harness that’s the pain. But yes it easier to reach things with it off
Cuz my lb7 is stock and the turbo is so quiet
Rc 4 Life Yes it will make the turbo louder. I really am pleased with the hsp system
Dirty Money Garage 3 inch horn or hsp 3.5 inch horn?
Rc 4 Life 3.5 HSP is my recommendation. It’s a bitch to get in but worth it
So a cold air intake and new horn will make the turbo louder?
Rc 4 Life yes, you can also do a turbo resonated delete and a ppe boost valve
@@MrTrump-hx4lb resonator doesn’t do anything just don’t be cheap and just buy a intake
Just bought one this past September. Injectors went out 3 weeks after I bought it. Thankfully I got a extended warranty with it. I bought a bull dog lift pump immediately. Still at the stealership though they been dragging it along.
Good call on the lift pump, I did the same for my LB7. When you finally get your injectors back, performing a diesel purge every once in a while will help keep your injectors clear of carbon as well as freshen up your fuel lines. Come peep my channel if you wants tips on performing a diesel purge. Best of luck and congrats on getting an LB7!!!
I bought one 2 months later head gaskets went uot🤦♂️
Any issues with check engine light without cats?
Doug Bauer The light would come on but no issues. All you have to do is put in spark plug Fowlers and connect them to the O2 sensors on the pipe put them back in and get rid of the light.
how do you control the tunes through the edge?
Reese LB7 When you get if I live flashed Into the computer of the truck you have the option of a DSP five switch or you can use the insight go to the settings and turn EFI live on and it should control it if it’s not hooked up to a DSP five switch already. If it’s hooked up to the DSP five I don’t believe it will work on the edge . Hope this helps
i figured it out lol i didn’t know there was an EFI Live setting on there
