just got back from taking it for a ride, still feels like you turn the key off when it hits 6300 rpm.

guess it's time to change the springs and see if that fixes it.

sorry for not updating the situation guys. i changed the valve springs and have not gotten to re dyno or run the car at the track since.
before the springs the car went 11.8 @ 122 shortshifting at 6300 and a 1.95 60' time. 10's are definetly in the future. i hope to get to the track next weekend to test it out.
i will post up an update as soon as i have some info.
