    Hello all 👋🏼, I’ve got a 2016 GMC 2500Hd that I’ve had for a year and am now wanting to do a full delete. Who is a recomendable tuner? Contacted PPEI for an ez Lynk but said they don’t offer emissions removed tuning anymore. Who are you guys using?

    Hello, first post here. Bought a 09 LMM Silverado a couple weeks ago, my first Duramax. Previous owner has some tunes on it with a DSP5, only info he could give me was that each tune would progressively add more power. He claimed the first one above the stock one was 500 hp and the highest one...

    I just recently had some work done to my LLY. It has regular ol EFI live with a DSP5 from Kory Willis. I’m looking to change up my tunes. Unfortunately the tunes were uploaded via laptop and my tuner doesn’t have my stock tune on file. I’m looking to upgrade to an autocal, that way I always have...

I bought a 2014 gmc 2500hd that was already tuned with a H&s mini maxx but the previous owner didn’t leave the mini maxx with the truck so I was wondering if I buy a new mini maxx and install the tunes would it fry my Ecm since it’s not the original one...

  13. General Discussion
    Sort of a long story I will try to keep it simple. 02 LB7 just got out of warranty. Decided to pick up a used Hypertech programmer because it was really cheap. Turned out the VIN was locked. Talked to a few guys and they said that I could have the dealer cheat it by flashing my ecm with the...
