also if you payed attention to the fact that im using a fpr then you would know that 45psi is a base pressure
yes i payed attention, your on stock injectors, with fpr, your also running 45 psi base with stock injectosr on a pcm thats tuned to run at 58 psi, so all the time that your not in boost your fp is to low for stock injectors and the pcm is jacking up your fuel trims to make up for the low pressure. sure the wot afr may be ok, but the closed loop trims are way off. and unless you just like the look or need the extra room the stock air box makes 355hp with s3 so it's not over working your turbo,
if your going to bring up rrr's then the people who might follow your advice need to know that, to use them, you also need a return line and a modified fuel filter.
with a base of 45 psi and a rr of 1-1, your fuel pressure is below the stock 58 psi untill you reach 13 psi of boost. so, to correct that and give proper fuel trims, you either need to raise the base to 58 and use a safc to tune. or use larger injectors for the 45 psi base, with your set up ptb is even more lean than normal for an srt-4.
