My buddy is looking into buying a duramax here pretty soon, probly on 01'-04'...he was wondering what would be the best programmer/chip for all around performance like horsepower and smoke??? please everyone put in suggestions and what you like on your D'max.

THANKS!!!

 

EFI Live isn't going to be the cheapest route but the you'll be hard pressed to find anything better.

 

Well, your buddy needs to figure out just how far he wants to go before he decides. PPE is hands down the best hand held out there. It also will net you some very good milegae. If you are looking for all out performance, then EFI Live is the way to go. If he has any questions about either have him give me a call.

PPE for plug and play but its hard to beat what efi live can do.
