I bought this tuner and i up loaded the tune that americanmuscle gave me ( 93 Octane aggrestive tune) and i was wondering if i could maybe twik it by doing something with the spark or maybe adding fuel like running 2% richer.....
there is a difference when i put it on the car, i espesicaly like the 2 step at 2700
