Yeah thats what i mean, rev limiter at 6800. A P72 which is a GSR ECU, should hit rev limiter at 7200 stock, correct??? Im not sure if this ecu is even chipped, think its a stock GSR ECU. The guy who put the LS/VTEC in told me to get a P72 so i did. So who knows........Any More Ideas???? Thanks for all you guys help.
