[Myron Piatek]

Taller front tires, a little stiffer carb return springs and make sure your routine is staging the car as shallow as possible.

Launch at a lower rpm - maybe that's what Jim meant by lower stall.

Are you at least consistent with your redlights? I always footbraked, but a practice tree helped my consistency even though I practiced with its button. Mechanical changes to the car will be more consistent than trying to do it physically.
