INSTALLED SOME BBK SHORTY HEADERS LAST WEEK, YESTURDAY GOT A CHECK ENGINE LIGHT. RAN A DIOGNOSTICS THROUGH MY PREDETOR AND CAME UP WITH P2096 POST CATALYST FUEL TRIM SYSTEM TOO LEAN BANK 1. RE ENSTALLED MY STOCK SETTINGS AND ENGINE LIGHT WENT AWAY. LOOKS LIKE I MIGHT NEED A CUSTOM TUNE. ANY ADVICE WOULD BE GREAT THANKS.

Reload the tune and see if that code comes back, if so, you'll need a custom tune, but it may be an exhaust leak on the one side.

i'm betting it's an exhaust leak.
