AdamB Posted September 28, 2014 Share Posted September 28, 2014 They are always a nice item to have because it allows the tuner to maximize your fuel setup, otherwise you would have to keep going to larger and larger injectors to provide the right fuel flow for your setup.

mikey4410 Posted September 28, 2014 Share Posted September 28, 2014 Well if your running for instance a td04 at 0.8 bar I believe u can run a stock rrfpr.above this you may well need a rrfpr.however if you run aftermarket ecu or piggyback I believe you can stick with stock rrfpr even running a td04 at 1 bar plus as a ecu can adjust for your extra fueling.Speak to your tuner if in doubt as they can advise accordingly.
