Yeah, too rich. As you should know by now, the safc doesn't allow to change fuel settings under boost in our cars and to start off, you are running stock idle fuel pressure on 50% larger than stock injectors. It's not a particularly good combination as you're finding out. Honestly I'd say you're better off running 5-7psi on stock injectors until you get an sfmu setup. I'd also say sell the safc to help fund the sfmu.
