So i have a 2001 S10 with a 5.7 running a express van tune on a P01. We are planning on doing some racing with it and i have it running real good for a first time tuner. My confusion from watching other racers on the strip and some of the terms they use and i'm not sure how they do it. i hear them taking power away from the start to get better tractions or adding power on the end of the track. How, are they doing it with the timing, torque management, trans pressures, etc. Any help or direction is appreciated.
