Raising RPMs above 7000

TuneECU may have a different maximum than Tuneboy, which Carpenter uses. And as has been said, there's no point without the proper tuning and appropriate hardware.
 
Point taken. I try to shift a 6500 since that's where the power seems to start falling, but 1st goes so fast I sometimes hit the limiter. Just wanted a little more before bumping it. Thanks for all your responses.
