Turning Up An L5D +240rwhp?! 

That’s crazy you can get that much change in horsepower just with a tune!

Also consider, L5D oil cooler is smaller than the L5P. I'm not sure if it's the same heat exchanger innards as the LML, but it's not the same as the 20+ L5P unit. This is worth knowing for guys that are looking for a junkyard L5P oil cooler to put on their older duramax...the L5D is not the one you want.

Showing your age Nick...at least here in the salt belt...i haven't seen a Yugo on the road since the 90's. lol...good stuff...thx for sharing!

Absolutely amazing

Just what it needed, and maybe air bags. 🤙🏻

Just FYI, I have a bone stock 2019 5500. I was doing OTR hotshot with it. My combined GVWR was 40klbs truck and trailer and while I usually stayed under that by a bit I had no issues towing in that weight range with a stock truck. The truck is more than capable to tow factory stock. I never once felt I was being "out towed" up a hill as I could easily pass whoever I wanted even heavy. Also just to note, I'd estimate 85% of the miles on my truck were in tow/haul with the engine brake engaged so it was bought to tow and that's what I did with it. It lived its life with a 40ft Big Tex 25gn hooked to it. With that said, my truck has 150k miles on it now and it developed an emissions code p003a which appears to be something with the turbo vanes.. I loved the truck and it's been mostly trouble free but this single breakdown will stop me from buying another GM product because they've locked the computers down on these trucks and unless you have expensive computer equipment you can't fix them yourself. To add insult to injury, every single dealer I've called is a 4 week wait for service because none of the dealers will hire more than 1 diesel tech it seems and not all dealers are authorized to work on the MD's. Not even international who sell the same truck just rebadged can do anything with the computer. As a result, the truck being down almost put me out of business and I had to get another truck to replace it. Never again will I buy GM over this. I'm right now paying $1k/month for a truck sitting broken down. GM's greed killed an awesome truck because they want to force you to take it to a dealer for repair but won't even hire enough mechanics to fix them in a timely manner.

-Will the mods you performed void warranty? If so, -Could you simply install an L5P ECM with the L5P turbo and essentially have an L5P (injectors too if necessary), then flip back to your L5D ECM for warranty dealings?

We went from a 92 chevy with a 366 big block so now that we have a 5500 dump truck its a power house stock😅😅😅

I'm thinking of ordering one of these. Can you do this on the 2024s as well?

Can you do this on the international cv chassis?

I’m very interested in a tune like this for my 2021 5500 but I’m located in Commiefornia

What’s the mileage difference for your emissions compliant tuning?

Can power train from a 3500 just be swapped in?

I have an 08!!! I cannot find any research about it will my twin turbo kit and 60%s from my LMM work ? Lol

Can you help me with a hp increase kit for a 2024 International CV 15? Factory is 330 hp. Would need500-600.

Does the top speed change at all after tuning?

Aren't the fuel injectors smaller than the L5P as well?

What is the difference in your tunes compared to deleting the truck and tuning it?

A competitor did Really really close same numbers but with only 62mm. Why isn't this one more, being 2mm more?

What does this tuning cost?
