    I have an Edge CTS that has been in my 06 for about 10 years. I traded it in a '21' DMax yesterday and removed it. Can it be used on the new truck either as is or can Edge retune it for the new truck?

    Hey everyone, I'm new to the forums, and relatively new to Desiel tuning. For better or worse, I bought a pre-built/tuned 2008 Sierra 2500 a couple years ago with 150k miles. It's been a good truck overall, BUT I've had a few issues with it I'm trying to sort out. First, a little background of...

    I've been looking into deleting my 2016 GMC 2500 Duramax and wanted to see if anyone had suggestions or comments. I'm planning on ordering a 4 or 5-inch straight pipe exhaust and GDP tunes on an EZ Lynk device. Would this process be as simple as taking the truck to a muffler shop and having them...
  10. Aftermarket Mods.
    Hello all! New to the forum. I have a Mini Maxx that will not change vehicles after update, nor will it allow firmware update. It has been VIN unlocked, it isn’t bricked either. I have read that even if you can’t change the vehicle, you can still upload and will identify your vehicle. Problem...

    Hey guys, I’m trying to find out who does good tuning for efi live in the Orlando FL area? Or just who still does good tuning for EFI in general. There’s a lot of companies and I’ve seen a lot of mixed reviews. I’d also rather have it dyno tuned if that’s possible with EFI so there’s no...

    Hey guys! First post here. I got an 03 LB7 a couple months ago and I'm thinking about getting a new tuner. Right now, it has an edge juice with attitude control module.

  16. 07.5-10 LMM Performance Parts Discussion
    My mechanic buddy says that a lot of my problems with my 07.5 LMM stem from the cheap tuner that the previous owner had installed. He says I need a tuner that can delete other tunes (the one in there now is just a switch wired into the PCM from the looks of it), and suggested a mini maxx, but...

    I see a lot of guys making 50hp tow tunes, 80 hp tow tunes, 150hp race tunes and so on, so how do you know the HP for the tune when you create it? Is it just based on what you know a truck with similar modifications has will do or is there something in EFI that tell you this? Thanks Matt
