You have to figure out if you are getting more air than the computer is detecting, which would most likely be MAF sensor reading maybe MAP. Or alternatively if less fuel is being delivered than commanded like from low fuel pressure or clogged fuel filter.
But before we get too involved in diagnosing mechanical problems tell us about your tune. You dropped to a 2.8 pulley, did you have your tune adjusted to compensate? If you had a "bad" supercharger before you might be moving more air than you were before which can cause a lean condition if your tune wasn't adjusted.
