    Exclamation Gp1800 stage 2 not going past 7800 rpm help!

    Help, i have my gp 1800 stage 2 flashed and its not going past 7800 rpm. installed i have

    1/ maptuner x stage 2 flash
    2/ solas 13/18 impeller
    3/ riva power filter
    4/ riva ribbon delete
    5/ riva pro series cooing lines
    6/ throttle body mount upgrade
    7/ engine breather upgrade kit
    8/ riva rear exhaust
    9/ riva ride plate
    10/ riva pump seal kit
    11/ riva intake grate

    I ride in Miami florida so weather is usually warm but I don't believe warm enough to rob me of all those RPM.
    Ski starts on immediately without any issues always well maintained.

    What tachometer are you using and what GPS top speed are you seeing at 7800 rpm?

    If you have the ability to change your tune....remove
    the tune back to stock...reinstall a different tune.....see if that works...

    I agree..... I have pretty much the same set up ad you minus the intake grate and pro cooling and I'm hitting 8620 rpm and 81-83 mph. I am also using Deals tune but you should be closer to that range.

    I agree, I just noticed it wasn't on your list also BOV .. Actually was thinking boost leak and thought it may be your BOV not closing completely but when looked back at your list noticed they were both missing
