When do I need a RRFPR

I have a questions for you guys. I know this isnt a single turbo questions but most of you guys have been thru this so I thought I might could get some good answers here.

At what point is a RRFPR needed? Is the stocker good for a certain hp or boost level or what? I just need to know at what point I need to start looking into upgrading it.

Thanks guys,
STEPHEN

You never "need" it. It's just an option (if combined with a serious fuel pump) to take if you want more fuel out of your existing injector setup.

I agree. I don't think you should ever use one ... assuming you have proper engine management. Just let the ECU handle all the fuel requirements in the proper way.

Stephen, I had this same question since I am going single. What I will end up doing is I got an upgraded fuel pump, bought a set of spare injectors and will have the primaries cleaned, calibrated and balanced and the secondaries likewise, but bored to 1300cc. I will control it all with the PFC. (thanks to DCLIN).
