Raced my friends GSX, he has alot of mods on it, turbo timer, headers, exaust, boost controler "at 12psi" down pipe, Vs my 96TA A4 conv with only a borla exaust

Raced from a 50 role, we were dead even up untill about 95, then i inched ahead of him to about 110,

Trying to think what else to get for speed. i know the conv is heavy and all but its fun. But i have like no traction below 40mph
