you can go faster, i ran 12.6 at 109mph at 14psi letting off up top because the car felt dead (i was having boost controller issues i was really suppose to be at 20psi) this was on hoosier dot radials with an ok launch i kinda just rolled out
i preload alot (hard to do with the b15 tranny sometimes) and i do a 2nd gear burn out, i went through the water because the hoosiers are really a slick in radial clothing i think u should go back and get a crack at it
