judging my AFR's, im going to rule out plugs as a cause for lower numbers. when was the last time you changed em out? oil will effect it but not terribly. im thinking a major thing here if the cat, air filter and MBC. get a K&N filter and get a reflash, remove cat and go hi flow or no cat and get the eboost2 or any EBC for that matter. Also on a side note, you dyno'd your last numbers @ steeda which is a mustang dyno. from what i know the mustang dyno inflates numbers which we clearly saw in comparison to last year for peoples pulls.
