We've tuned my IC SC R3 to .82 lambda (12 AF) to give a bit of cushion against detonation at max boost of 14 PSI (7000 RPM). IMO, by using a boost controlled fuel pressure regulator, we can lean that out to the 12.5 - 12.8 range which will result in slightly more power.
Modern boost indexed regulators (FMUs) can maintain true 1:1 pressure at idle (where my SC boost is zero) but are completely adjustable in their pressure curve to give as much as 12:1 fuel pressure at max boost. Another upgrade for FA R3s.
