Andrave. 10:1 A/F is "hella" rich, not lean. But that doesn't matter.. because it's a 10:1 rising rate fuel pressure regulator.
RRFPR + S-AFC = Hard to tune. And you'll need to retune if you add another pound of boost because your A/Fs will be off. Remove the FMU (RRFPR), add a Walbro pump, and go off the S-AFC alone.
