other than the programmers, which I dont totally trust after one erased my computer on my previous vehicle, what performance modifications would you suggest for a 4.8L 2007 Chevy 4x4
If I go with exhaust, I want a good sounding one, but nothing that will make me not be able to hear my radio :lol:
Air intake??
headers?
I dont want anything that will take away from my fuel mileage, but suggestions to add to it are always welcome - and before anyone says let off the pedal a little bit, I tend to drive with a light foot anyway.
