    Is there an aftermarket ECU that doesn't require valve upgrade?

    Is there an aftermarket ECU thats higher than the stock ECU rev limiter, but keeps the RPMs in a safe range where head work is not required?

    Is it just on the X skis or can the 215 platform run the 8,400 rpm range?

    Jarrett I think stsperformance is trying to sell his reflashed X ecu that is set for 8,400 rpm.
    He was running 50's with rrfpr and was right at 78 mph on T-X. Oh yeah it was with a 2Rude, but I am sure with x sc you could run same setup or stock injectors might work with rrfpr.

    I am only talking about the Xs. Don't know about RXPs. I would still think about doing retainers and/or springs and retainers. On any of the AM ecus, I would still have my AFR checked. Its never plug-n-play. BET.
