    Riva ECU and mini rude upgrade will need RRFPR?

    Im planning in upgrading my X-charger to mini rude with 4" air...
    I already have Riva ECU with 50 injectors....

    thanks in advanced.

    as long as you don't ride in cold temps (below 70F) the ECU should compensate for it without the RRFPR
