But what about setting it to 2.5 bar (or less) at idle? Isn't the whole point of the RRFPR that will give you the fuel you need when you need it? Is there a bottom end to how low you can set the RRFPR? Is there a formula that says for x amount of boost at y rpm (also, by gear?) set the RRFPR to z bar at idle? My peak boost is at WOT in 3rd - 5th gears.
I have been running the 30# injectors with a 3.0 bar FIXED FPR for about 7 months now, and only recently has it started to run super rich. It was always rich, but not as rich as it is now. Strange. Brad (of George's) suggested that it could be fuel leaking through the vacuumed boost line of the FPR, or a bad connection at the engine coolant temp sensor.
I think I'm due for the RRFPR (see post above). I need the added fuel up top (at 22 psi of boost), but my richness at idle sucks. The idle itself has not been disturbed by this set up, though.
