Qtr mile time,,,need quicker times..wat should i do?

The tires don't help, for sure, go with a stock height tire, see what happens, or reprogram the computer for the 20s height. Get rid of all excess weight, and keep the skinny pedal down, you said it was weak at low rpms, you have a stick, keep the rpms up, launch hard, keep the skinny pedal on the floor, and practice getting your reaction time down, many races are won before the first ten foot
