whats up. i bought my type r about 2months ago and it had comptech exhaust, headers, an a ecu. does anybody have any info on this set-up. what i notice is that my car hits and if not comes very close to 9k rpms. is this bad for me to do or is it safe. any of ur information is aprreciated.

 

If thats all your car has, there is no need to rev past the 8400 limit.
your just taking the chance to hurt something beyond 8500.

 

The Comptech ECU raised the rev limiter slightly. You should be fine. Keep in mind that the comptech parts were designed to NOT void your factory warrenty, so I doubt that any of Comptech parts will hurt your car.

Fuel cut-off is 8650, they only raise it 200rpm. You are safe there. You are over reving the car if hitting 9grand
