I am suprised as to how much differences there are in the 04 pcm compared to the 00pcm. But i manganed, changed the shift points, rev limiter, adding timing until KR showed its face. then backed it down .5*, shift times to .3, Top speed limiter to 125, goin to take out TM when he gets his shift kit and servos.
But compared to stock, this truck has woken up!!!
Ill have to get exactly what i have done, but i want to know what else i can change. To possible get more power, and better fuel mileage for him.
The truck is Bone Stock, we are puttin LS1 Fans on this weekend.
