60' times in the 2.x and you don't have traction problems? I'd focus on getting that down to 1.8. .10 in your 60' is supposed to be worth .20 in the 1/4.

I'm brake stalling the truck to 2400rpm and launching it in 4wd I have no wheel spin at all. It is a 5500lb Double Cab 4x4 Z71 Silverado. Tune only I would say the 1.94, 1.96, 1.98, 2.01, 2.03 60ft times are pretty good being stock the trucks 60ft was 2.13 with a 15.20 1/4 mile time.
