I use 1st gear start. Don't flip tranny completely, but enough to stretch 1st gear so that you start 1st and shift to 2nd quickly, around 25 mph.
To do this: reset tranny. shorten final gear (move to right). move top speed to minimum. lengthen final gear (move to left). Work this process until you are getting off the line quickly - try to get 0-60 to 2.6's.
Once you are getting off the line, work remaining gears to stay in peak power zone on shifts.
Also:
Suspension: Min front height, max rear height. Max +toe on rear, some -toe on front.
