Bolt On lt1 a4 times.
to OP leave the car in (D) Drive and let the computer shift the car. you wont be able to shift faster then the computer.

As far as the computer goes - at the track sometimes I had to manually shift it a bit because it seemed like my computer wanted to shift early with a bit of wheelspin - perhaps that is a bit of a tuning issue
Just my opinion... Dont kill me
