2006 Dodge 3500 turbo making a lot of noise when I moderately push pedal ( whining up noise) let off or just cruise no noise. Had truck since new only started this after I put new ac on. I changed out water pump sat and took the turbo pipes off to see if there's a hole in the rubber connectors, none. Maybe a bearing? There's an electrical sender on the bottom of turbo housing, I'm guessing that's a waste gate controller, could that be a problem?
