Im looking at getting a 2004 GMC 2500 Duramax I'm not sure if its its the half or not what would be a good chip to put on it. it has 4" exhaust from the turbo back i'm new to having my own diesel. i'll be pulling a smaller camp trailer and a livestock trailer and just for fun also.

I prefer Dorito chips.

Although I would prefer EFI love as programming for it. Is it a LB7 for sure or LLY?
