MIL light comes up with a P0174 lean right bank. Would this be the new CAI (air leak)or will it disappear when I get my tune in 2 weeks? Lingenfelter is the CAI.

It's probably the headers. From what I've read the headers will make it run rich at idle and lean at WOT (or vice versa). I'd stay out of the throttle until you get the tune to take care of it.
