    which ECU are you running? with either of those SC options you listed you need fuel injectors

    Stock ECU - 42 lb
    RR ECU - 42 lb
    Riva ECU - 50 lb

    I know it's more money, but if you are going to go through the trouble and expense to upgrade spend a bit more and get the Riva S3 SC.
