    07 RXP going 81.6 on a stock ECU

    First time to the water and my 07 went 81.6 on the stock ECU turning 8,200.I have the following mods.


    Supercharger Engine Tech big boy from Race-Tech
    Head work from Race-Tech
    4" Kanaflex intake(I going to try my own intake when the boat is done)
    Thru hull exhaust
    OPAS is still on it
    Free mods
    My ride plate that I use for close course racing
    My own RRFPR(little on the lean side but why tune when I'm not done the build)

    I do think I could gain 1-2 mph but I hit the setup pritty good on the first run.

    Sounds like a big charger and a rideplate mod is the key to getting the most out of these skis.

    Forgot Mac boost intercooler.(almost the same as the XS)
    81mm ring
    15/20 with 2mm added


    I'm running lean in the cold weather but 42 injectors with 65lb base fuel pressure.In the heat that should be fine but with the cold I would switch to 48 but I'm not done yet.

    I'm wondering if anyone has ran faster on a stock ECU.
