    You will have to purchase a 17 lb supercharger wheel and Riva Racing fuel rail and 100lb injectors.
    Then change your Maptunerx yo the stage 3 tune....good to go.

    The Riva stage 3 does not require a map sensor

    I just got off the phone with Riva ....the 3 bar map sensor is ONLY required for stand alone or aftermarket ECU. People that want to make their own maps.
    With the Maptunerx it is all taken care of...with the supplied tune...
    I have been running it since 2017....

    Yes....with the 17 lb wheel.
    I think you will have to go with a Dean's Team reflash as Riva does not offer a tune with a 19lb wheel.

    I also have some cam gear mods...
    Solas 12 vein pump and twin impeller.
