I have a 2009 Cobalt SS with the following mods; K&N Typhoon SRI, Injen Intercooler Tube, MPX 3" SS Exhaust w/Spun Cat, MPX Pulley and a Superchips Cortex program with a 91 tune. The problem I'm running into is I'm throwing a CEL. I ran a diagnostics which revealed the following engine code: Engine Code # P2096 Post Catalyst Fuel Trim System Too Lean bank 1. Has anyone experienced this, if so, any suggestions on how to rectify the problem.

Thank you
