You will read some post with I shift at 6500 NO problem.(Untill the day)
In 1-2 I set it at 6200
2-3 at 6300
3-4 at 6200
REV limiter at 6400.
I didn't raise my rev limiter in fear of damaging a stock motor.I'm sure every car may be a little different though.
I take it to a local 1/8 track and tweak it there.
Good luck.
