6A MSD,MSD blaster coil, VERY GOOD traction on motor spins less then a half a car, i think the converter is a problem too it stall up to about 3500-3700RPM and i think the gt-40 setup powerband range is from 2000-5500RPM by stalling at 3500RPM takes away alot of low end power i think...shift points are 5600 going to second nd 5700 going to third... was at a shitty track they didn't give out short times or mph...THAT SUCKS!!!
