Are you 6 spd guys going through the traps in 4th or 5th? I've seen some videos of the stock cars shifting to 5th gear. I didn't, I stayed in 4th. I read that the stock limiter comes in around 6700rpms, which if thats the case I was on the limiter at the end and maybe between shifts. Wouldn't I have heard the limiter if it was hitting it? BTW my car has 3.73s.
