Had an awesome night at the track, conditions were just ok (70 degrees 70% humidity) but I ran very consistant numbers that supprized me! My only mods are intake and exhaust on my 97 MN6 Z51, factory freak possibly? Also if I can get that 60' down to a 1.7 I should be looking at a 12.4-12.5 which is DAMN GOOD for such little mods!
