So my uncle has a 16 Denali and it is currently stock but he goes back and forth about tuning and running exhaust all the time as he was a race car guy so he still has the itch. I know he will NOT go wide open with EFI LIVE and play with it so i need to buy him a simple tuner that he can play with and may or may not go to straight exhaust. I am sure he has to be sick of dumping in the fluid by now but he may play with the tuner for a bit before going all the way to getting ride of the DPF and Cat.
Sooooo what do you think is the best cheaper tuner for him, he will not be racing but fuel mileage will be a factor and sooner or later i will be able to talk him into throwing all that stock exhaust away.
