GM Tech Systems or HPT
I've been doing some research and have come up with very little as far as tuning hardware/software for these cars, and I know that WAMS is no longer an option since they have stopped supporting the G6. I also know that HPTuners isn't the best for this platform, but is that my only option?
My other question, is, is it possible to tune with a GM tech 2 or 3 tool? I know they will allow me to access the speed limiter (which has already been done on mine thanks to a friend) and a few other things like reprogramming a stereo unit or key fobs, but what about engine management?
I have access to the programming and tuning knowledge that's needed, just wanting to know what will be the best way to apply it. The one advantage I have is the ability to do about 90% of the work myself, and the other 10% would come from friends that own shops and are willing to help after-hours with the more complicated stuff.
And I'm well aware of the challenges that come with trying to squeeze more performance from these cars. I think those challenges are the very reason I want to modify it in the first place. There's a lot of room left to be the first to do a lot of things to it. lol
