Check Engine Light, Running too Rich? :confused:

I just went to emissions and failed because a check engine light, the troble code is P0172 and : System too Rich. Help me out!? Maybe just a re-tune?
 
Are you running an FMU with that supercharger ? If so disconnect it and if you have an adjustable regulator lower the pressure about 4 pounds and retest.
