I got my 60,000 mile maintance done last week and today I was accelerating and at 80 mph I hit a wall. I thought i had really ****ed something up but after some quik checks I realized it was sometyhing with my turbo cause i was getting boost, slowly, but my BOV wasn't going off but my engine sounded completely normal, thank god.
When i stoped to check all the bolt on's I found the ram air thingy wasn't lined up with the hole in the fender wall and the clamp after my air box was really loose. Fixed both of those and CEL went away and power returned. Glad I figured it out otherwise I would have had to demod and bring it in.
I'm still calling to complain tomorrow.
