To get the best 60 ft and 330 ft times you have to test the stall RPM and the shift RPM It wouldn't suprise me at all that you will see a big difference in the 60 ft times just raising the RPM on the footbake up to around 2700 RPM and higher I normally will try 2300, 2500, and 200 to 300 RPM increases each test until the car gets its best 60 ft times and reaction times. One of my old NHRA stockers would get the same results at 1200 RPM and 3500 RPM, every other RPM between would spin the tires
