Ok im getting my car back tomorrow and the motor has been rebuilt with aftermarket parts and stuff. so i put a new clutch in it and i just got a Heat Exchanger put on it but i cant get it tuned for 1000 miles because i have to brake in the motor again and the clutch says 500 miles to break that in so would i be alright not boosting and shifting at 300 rpms and nothing over that? until the 1000 miles are up??
