What exactly is the issue?

Have you tried a "Blue Driver" or ELM 327 attached to the OBD2 to see if there are any codes or trim reading. The Super Charger probably changed the Air/Fuel ratio. These devices just plug into your OBD2 (On Board Diagnostics) plug in receptacle.

Are you running premium fuel?

Have you pulled any spark plugs to see if they are burning rich or lean.
