Also, I know you said "stock," but I just want to make sure...you haven't changed your intake system at all, have you? Your MAF voltage isn't responding as aggressively as I would expect during your higher RPM runs.

The car actually runs "better" (still lean) on the stage 1 tune compared to stock, where my ratios get even worse.. im thinking the MAF sensor might be damaged as the issue only came up after i had another issue with the throttle body and a small plastic piece got stuck in it.. im going to take apart the intake and see if any gaskets or so broke as thats what the piece of plastic most likely resembled
