I changed my truck back to stock using my bamachips tuner yesterday, was on 93 torque program and driving home today my check engine light came on. I ran diagnostics on it using the tuner and it has four dtc codes come up.

Is this common when putting the truck back to stock and should I just clear the codes out?

 

Not sure about your particular problem, but I tell people to just stick some black tape over the Check Engine light. Works every time LOL, just kidding. Maybe someone who actually has a X2 or X3 can help you out.
