    riva X charger upgrade?

    do you just run the 50* injectors with the stock ecu?


  2. #2
    i got on riva's website and looked (i was on the green hulk store) it says 50* with stock ecu or with riva ecu.

    MY QUESTION: will the ski run/operate correctly with the 50*'s at part throttle and everything with the stock ecu?

    Your gonna be rich as hell in the low and mid RPM ranges with 48/50s on a stock ECU..You may want to consider going with the Riva ECU or a type of fuel controller..

    The boost does not come on till 6k or so with an RRFPR you "should" be able to run the x pro and just up the fuel with it so your not lean on top.
