    Where should my RPM's top out at?

    I have a 2005 RXP and live at an elevation of 2500ft above sea level. I am currently running the following mods:
    Jerry's Reverse gate mod
    Fresh air intake (my own design) with a K&N Filter
    RR OPAS block off
    Impro's 14/17 concord
    UMI steering
    Direct exhaust
    Blow-off valve
    Finger throttle

    I ran last year at a peak of 7800 rpm's with a 14/18 concord @ 68mph, this year I changed out to a 14/17 concord and got up to 7950 @ 70mph. My question is should I just keep repitching until I get to the 8300rpm mark?

    Any suggestions would be great.

    Thank you.
    JD

    If you don't have an ECU, than you should keep pitching till you get 8100 rpms, on either prop.

    Hey Everyone,
    I have to disagree with psycho rxp, at 2500 ft elevation I don't think you're going to get enough air to the motor to get the rpm.
    With my RXT it will do the same thing . At one of the lakes which is about 2500 ft elevation that all I see in rpm. But at sea level it will twist up to 8100 rpm .
