Im going back to the tuner and move up the rev limiter up to at least 7.8k.. now that im looking into it i have 2 friends here where im from that one has a CJ and revs to 8k, the other has an 18 mani and revs to 8.1k, and they have been on that set up for a while as well as they do track there cars frequently.Ya you can definitely rev it higher than that.
