    short answer is no but it is a good idea. what RPMs and psi are you seeing an where do you have your pressure set.

    RPM 8650. Im thinking of 8800. Pressure set . My rrfpr went bad
    I have vtech map tunner and vt data logger.
    Do I still need rrfpr

    bigger injectors need less psi so they are easier in the pump

    Assuming VT1100 and the tune is set up for those.... Yes run the big injectors with fuel pressure set to 60 at idle and static. This works fine up to about 17 lbs of boost.

    60# base at 17 psi sets those at exactly 43 WOT. That's hanging right on the edge
