    Low Boost with stage III charger......

    My RXP seems to be boosting pretty low considering the mods. Previous owner told me it boosted @ 9lbs, which I did see when I first got it but now I am seeing 7lbs. Not sure what the issue is, any thoughts?

    Current Mods:
    2007 Super Charger housing w/metal washers
    Stage 3 Riva Super Charger
    42 Lb injectors
    Riva Exhaust
    4" Kanaflex Air Intake
    Customer Spearco Intercooler
    Tial Blow-off Valve
    Riva Valve Train Upgrade
    Rotax Racing Thermostat Kit
    Modified Water Box
    R&D Intake and Girdle kit
    SS wear ring
    Solas 15/20 R Impeller

    I plan to run a bigger charger next year with head work done this winter. Should I aim for a new ECU or can I stick with the dual rrfpr set up? Does the Riva ECU require a rrfpr?

    Thanks!

    depending on the hours on your boat & the supercharger itself the slip moment is probably not up to spec to hold boost @ WOT! get her a out and get her checked! good luck!
