do you have a 96-98? 101 mph sounds like a PI headed mustang to me. im guessing 99-up. these mod motors are so hard to launch on radials. to little rpm and BOG to much and you kill the tires. i think i have gotton a 2.1 sixty for my best on radials. mostly im in the high 2.2s-2.3s. my slicks are on some ten holes.
