I have a Autometer tach with the same features , bought it years ago and don't know if it was named PRO Stock tach or not. From what I remember you set each shift point 1-2 2-3 3-4 . If you did use the first set point for burn out then the next could be set for the 1-2 shift and so on. I do the 1-2 shift when the front wheels come down. I myself never found that different shift points helped my car once passed the 2nd gear change. Do 2nd gear burn outs, launch about 4600 depending on the track and shift at 6800. Seems to be a happy RPM for my engine. Runs 10.30 at 130 mph consistently.
