    question

    well i ended up changing my 50lb injectors to 42 and now i dont have enough gas at wot, so im thinking of going back to my 50`s and puting in a rrfpr to take gas away, does this sound about right, or should i put 48`s. the 42s with my r&d fuel tuner are perfect intell wot then its 13.0 my 50`s are just to much gas, so i can just give less gas with a rrfpr, right?

    Re: question

    Sounds like you need 48s

    Pretty Sure you only increase fuel with an rrfpr.

    with a RRFPR u can lower the base pressure at idle and run bigger injectors and have it raise with boost so it can have enough fuel at WOT.

    not really the only thing ur gonna be able to setup with a RRFPR is the WOT AFR's cause once u dial it in at WOT u are stuck with what u got everywhere else, unless u are using a dual Reg setup with a BEGI.

    get a rude controler.. you can make it perfect every where..you can add and subtract..i run 50s at 50 lbs of base pressure and a rrfpr..and subtract a little at idle and add a little up top with the controler...and it is perfect...11.6 11.8 wide open ..13.3 13.5 idle ...and mid to high 12 off boost everywhere else...

    you have already spent more than it would cost on bandaids..

    r&d adds only..as far as i know..

    the rrfpr basically adds..yes it pulls a few lbs under vac ..but not really enough to make much difference...

    begi works but contstant tinkering and again..never perfect everywhere...

    50s you should be in the ball park with the rrfpr..but you will never get it perfect everywhere...i have run my ski w 50 and the rrfpr at 58 ish base..and was fine just a little rich right at idle..
