    Mark,
    The Riva ECU is mapped for 50# Injectors and good for up to 13.5# of boost..I dont know the specifics on what else you would need and I dont want to tell you false info...But seeing what you have going on you MAY just need a RRFPR or maybe 55# injectors???..Maybe one of the BIG RPM boys will chime in and let us know...

    i run a 2rude on my 07 RXP and i have the riva ECU and 50 inj. and the RRFPR is a must or u will blow ur engine because the ECU and the inj. wont provide enough fuel

    With stock fuel pressure (58 psi), running 14# of boost and 50#/hr injectors the max hp that combo would support would be approx. 295 hp. This is assuming the Riva ecu would command 100% duty cycle (static open) to the injectors at wot. I would say keep the 50's and get a rrfpr to dial in the afr at wot. You also MUST check your afrs with a monitor.

    This is correct. With the 2rude, Riva ECU, and 50lb injectors you will need the RRFPR for adequate fueling.
