My brother jut got a 11 gmc 1500 and is asking me to tune it for him. I am not sure what tables I need to be looking for. The truck has a wideband in it. Long tube headers, full exhaust , comp cam, and intake. Any help would be greatly appreciated.
I've tryed tuning a Tahoe and I researched and researched and thought I had it down and knew what to change but I couldn't get it to do anything different.
