Current A/F ratio is too high
D16Y8@7 psi, 12:1 FMU, MSD Inline pump, 270 cc injectors. Right now my A/F ratio is like 14-15 under boost. How can I bring it down to like 12-13? I assume by dropping my idle fuel pressure. Am I correct?

14:1 is way lean under boost. what are you using to measure your a/f ratios. lowering fuel pressure would definitely not be good. by lowering your pressure it would be even leaner. Less base pressure = less total pressure under boost therefore leaner. more pressure more fuel you get the point.
if the car is running good and you are going of your a/f autometer then you want to see green on the guage. i see it hard for your car to be leaning out that bad unless something is not hooked up properly.
