Another great video, Nick!! Moving from the 1/2 ton to the 3/4 gave me so much more confidence with the larger brakes, exhaust brake and just that extra 2k lbs of truck weight helps control the trailer better. The trade-off is that softer 1/2 ton ride missing with my Ram 2500 Cummins, but worth it to me when towing.
I became a diesel head when I was racing motocross in early 2000s. I had a 1500 z71 and my step dad had just got a 2001 LB7 and when I would pull my inclosed trailer to a track in KY and my half ton would use 3/4 of a tank round trip and when I got to use the LB7 totally stock it would only use 1/4 tank of fuel and from that point on I have only owned diesel trucks. Now I just need to get my 16 LML tuned by Nick lol
I went from a 1990 Chevrolet 454 dually to a 2006 GMC dually with a Duramax. I’ll never have another gas truck that I tow with regularly, it’s a night and day difference towing. No more foot to the floor trying pull a hill, and no more 4mpg towing. I’d only go back to gas if diesel was significantly higher priced than gas, or I stopped towing every other weekend with my Jeep and camper. And love your guy’s tunes on my LBZ, best upgrade I’ve made to the truck. Keep up the good work on the videos/podcasts guys!
I have the same '01 LB7. I'm still waiting to hear back from you guys if you have a Spade TCM tune with one with the overdrive lockout feature enabled.
Great comparison Nick that's why I stepped up to a 3/4 ton from my half ton I don't tow very much but in the near future trading up to a 5th wheel 10000 plus pounds pounds knowing I will need A diesel
My 04 6L gmc gas would scream to 4500 rpm going up antler hill pulling our 27’ bumper pull. Now got 05 diesel tuned by nick and a few other goodies. 😇😇
I know people love to talk about mpg differences but rarely talk about total costs of maintenance. In my area, diesel is about 15% more in cost. So that needs to be factored. My gasser rarely needs a fuel filter change or any type of upgraded fuel system. Oil changes are a good bit cheaper. Any parts are significantly cheaper.
Great one Nick 👌👍, l have an LBZ WITH 6-speed Alison in my Yukon,love, love the? Well everything about the 2500 series trucks, comfy ride, ease of handling and the power ! I have owned turbo gas cars, even twin turbo gas car , lots of power when empty! Poor gas mileage all the time. Love your show and knowledge, please keep the info coming, even old stuff refined! My goal is more power, a 64 ? or 67 with a compound buddy, a 488? or larger, I'm after power and reliability, something that is so possible with the diesel platform. Thanks again Nick.✌🏻😛
I’m really surprised that the Titan XD with the 5.0 Cummins wasn’t more popular. I kept hearing people talk about how they were to expensive and that you could find a gas 2500 for the same price. What they didn’t say was it was an XD Platinum Reserve vs a close to base model gas 2500. I bought a new 17 XD SV 4x4 5.0 Cummins in January 2018. $36.6k.
@Steven Seagull should watch the video of it vs the 16 model F250 ford Powerstroke. The XD squatted less. Legally you can’t tow more, but as someone’s who’s towed 15k and 3500lbs in the bed of the truck, I can sit here and tell you it can do it, and do it without looking ridiculous. I’ve seen 1/2 ton guys saying their trucks can pull no problem, but you see them squatted to the ground. The XD doesn’t do that, and can actually stop with their 3/4 ton brakes.
I have an old half ton chevy and recently sold my common rail cummins. Had to replace the injectors on the cummins and they costed $2200. Thats pretty much the cost of my old ls engine. I say get the diesel if you actually need it. Too many ppl buy them to just drive around town or haul an old Honda civic
@@gilbertperez1337 I am not so sure anymore it would be terrible mileage. I just traded trucks and went from a Duramax Colorado to a Silverado 2.7 turbo. The mileage difference isn’t as much as I originally thought it would be, daily driving and towing. The cost of the 3.0 Duramax was a little out of reach for me. I have been very impressed by the 4 cylinder turbo in this Silverado.
If we were to test a turbo gas half ton it would probably be the 3.5 L ecoboost. It’s the platform that we have the most experience with tuning in the gas world. I suspect a tuned eco-boost could hold its own against a stockish LB7 or LLY towing so long as you don’t need the stability of a 3/4 ton truck. They get thirsty towing too , though.
I have always had only gas cars and trucks but as of this year I have literally converted my 97 f350 crew cab dually to diesel. I put a 12v in it out of a 96 school bus and love the fuel mileage and power to pull just about any thing I need. Diesel for the win here.
there isn't one. you can not tow with a big single in the rocky mountains without turning the sun dark.... or blowing your tires off... big single is for broke farm boys or race cars
This is a great video and a great breakdown on how diesel vs gas differs , however I don't think your comparing apples to apples in this video , it's hard to compare 2 vehicles in a different class rating as far as a diesel to gas. I mean you have a 1/2 ton gas engine and comparing it to a 3/4 ton diesel truck. In all fairness you should've used a 3/4 ton gas truck with the 6.0 or the 8.1 to compare with pulling the same weight. And in my opinion diesel isn't necessary unless your pulling heavy all the time. If your only pulling a trailer a few times a year save your money and stick to gas.
It would be cool, unfortunately very few 6 speed 8.1’s exist in the wild. We were really trying to hit a broader audience with this one. Shooting for guys thinking of buying up from a gas half ton. The big cubic inch gas trucks are a bit of a different breed.
Oh definitely, I brought that specific combo up as it would have at least a somewhat level playing field having the Allison. Loving yalls content. One day I’ll make it up there for some emisions compliant compounds and tuning on my 2016 g56 Cummins.
My wife is very used to the way a diesel pulls. When we have ran a gas engine before she always asks what’s wrong with the truck, why is it so loud and revving so high?
On a side note all of our work trucks that only carry fuel tanks and tools but never tow are gas motors. Less expensive to operate and get decent fuel mileage. All the trucks that tow equipment are Diesels.
So I bought a 2021 sierra at4 with the 3.0L and ive heard it from multiple people and heard it myself. While idling the truck makes a small ticking noise. Gm does not have a recall or a fix for it. Anyone have any info on this? Or possibly what could be causing this?
Towing with my Calibrated Power tuned compound turbo 14 Ram 2500 Cummins is unbelievable, Diesel is the only way if you tow regularly, if you tow once a year you might consider a gas engine but nothing compares to Diesel
I sure wish I could find more videos on turbo charging a 6 liter or a 6.6 liter gas engines for pulling trailers --- don't get me wrong diesel is the way to go but the drama with the DEF world kinda makes you think what would a gas engine with turbo do
We don't tow that often but when we do, it's often long hauls. we live in the mountains so I wouldn't consider towing with gas. At times, I can be towing close to max GCVW.
curious, you have the diesel tuned. did the gas truck have one of your gas tunes in it? if not do you think it would help the gas truck with the shifting and torque? i completely understand that it's never going to be a diesel. i have similar truck as the gas. i tow a 7x12 cargo trailer 2-3 times a year up north. thinking about getting smaller travel trailer. (under 6000lbs total) id love to see comparisons between stock and tuned gas 5.3.
For the sake of the test I had the LB7 switched down to one of the tow tunes. It probably had the power potential of a stock L5P in the video. Certainly a tune on the gas truck will help the situation (especially an ecoboost or similar turbo platform) but for the sake of this comparison tuning the 5.3L N/A is not going to significantly change the results.
I thought 650 hp was enough to window an lb7 or lly block. Does this blue truck have upgraded rods & head studs or are you just trying to blow it up for fun?
You hit the nail on the head Nick, I had a 2003 lb7 and it would average 16l/100km towing my camper. Decided I didn’t tow enough to justify a diesel and bought a 2013 6.2l Silverado with the full tow package (10,400lb rating) and found that it burns 1/4 tank in 80km. About 28l/100km. And that’s babying it, so needless to say I’m in the market for another used Duramax If anyone’s selling lol
All Genersl Motor engineers responsible for cooling the engines should be fired. I have mainly run GM for 35 years s d never learned my lesson. The can't keep coolant in them, when you buy one you better budget head gaskets every 40 thousand miles. 2012 Duramax 120,000 miles, second head gasket failure. Absolute junk.
@ 1:56 Diesel is in "tow/haul mode" and stays in tow/haul mode on. When the 5.3L gas stays close to the same RPM in "tow/haul mode" you turn off "tow/haul mode" (@10:45 ), to purposely make the RPM way higher and show the "dramatic difference". How is that "apples to apples " when Diesel is running "tow/haul mode on, and gasoline is running "tow/haul mode" off??
Man I love Nick's videos. He's clearly so knowledgeable and just level headed, technical and non emotional doesn't seem given to hyperbole.
Thanks!

Well they didn't come with a Cummins
Love it. Agree with the "drama" explanation.
We need to bring back diesel cars in the USA!!! Wish I never turned in my Volkswagen Jetta sport wagon TDI.
You should repeat this video with the compatible 1/2 ton 3.0 duramax included to see if that bridges the gap better
Yes!!

Hey Nick, could you do the same with a comparison between the diesel and a turbo gas 1/2 ton. Please
That would be so bad in fuel mileage haha

@@briannelson2818 I was thinking about a turbo 5.3 or 6.0 I should of said that

That can be arranged
@@Duramaxtuner that would be awesome and pretty informative
I would like to See a towing comparison between a single and a compound setup on the lb7.

Totally agree with you Christian, it’s not an apples to apples comparison. I think I acknowledged that fairly early in the video.
It would be cool to have an 07 8.1 vs LBZ, both with 6 speed Allison’s.
Do like 6,000 pounds and then 12-14k and compare the dynamics.
It would be cool, unfortunately very few 6 speed 8.1’s exist in the wild. We were really trying to hit a broader audience with this one. Shooting for guys thinking of buying up from a gas half ton. The big cubic inch gas trucks are a bit of a different breed.

Diesels can pull more and better, no matter if they have the same HP than a gas engine. As Nicke mentions, the overall experience is better.
I've had an lly for two years now.. won't ever go back to gas.
Towing with my Calibrated Power tuned compound turbo 14 Ram 2500 Cummins is unbelievable, Diesel is the only way if you tow regularly, if you tow once a year you might consider a gas engine but nothing compares to Diesel

We don't tow that often but when we do, it's often long hauls. we live in the mountains so I wouldn't consider towing with gas. At times, I can be towing close to max GCVW.

This argument does not hold much water against the ford ecoboost engines
The eco-boost adds another dimension to this argument, no doubt. I wouldn’t say it is equal to the diesel but fits somewhere in between the two.
Diesel all the way
I thought 650 hp was enough to window an lb7 or lly block. Does this blue truck have upgraded rods & head studs or are you just trying to blow it up for fun?
It’s ‘On the Edge’ ;)
Morning, I am having trouble locating a tuner for my LBZ 2007 2500 hd classic.
Location Ontario Or. any ideas?
Motorops in Canada has them
You hit the nail on the head Nick, I had a 2003 lb7 and it would average 16l/100km towing my camper.

Have any pictures? Email me @ tiresmokehaze@gmail.com I know it’s corny, my spam email lol
@@dmaxman321 I’ll get some shot today and try to get them to you.
@@dmaxman321 I got some pictures sent yesterday. Just letting you know in case you don’t check your email often.
Wait so just some good tuning & a 67mm turbo can make this truck have 650hp
The truck will need a stroker CP3 pump and lift pump as well, but yeah basically.

I’m assuming that LB7 has fuel modifications in order to make 650hp???
I believe 650hp is about the limit on stock fueling. I'm sure dmaxtuner will have more info but they may not have time to respond to comments
@@kevinkalivoda3442 I thought 550 was max
It’s got a Stealth 67 and a 10mm pump. Basic recipe but it works.
