I recently got code P226C(turbocharger boos slow response) on my mp8, ive checked the turbo, checked the couplers for leaks, checked the egr, even bypassed the DPF/exhaust to see if it was clogged, open MP8 sounds AMAZING btw! It started last night with a really loud whiney noise when under throttle then i hit a pothole and it went "back to normal" noise wise BUT i was really slow picking up speed.

I look at my boost gauge and it gets 1psi pedal to the floor! Ill be doing a boost pressure test tomorrow but id like to know if any of you have dealt with this before? According to Mack changing the turbocharger will not get rid of this code and it might be a software update needed?
