I also have fuel injector duty cycle rwading to back this up (94% reduced to 86%). Is this a ecu learnning function in 3rd gen sti? Thx

How did you measure the AFR and was that past 60% throttle?
ECU learning is only ever done in closed loop, if its "learning" in open loop i would be worried.
That said, AFR's in open loop should be pretty spot on as its too late during high demand to correct. When you're on the noise the AFR, Timing, Boost need to be spot on otherwise you're doing damage or not maximizing power.
