Hook up insite and key on engine OFF look to see if insite shows the turbo spinning.

The turbo speed sensors can get cooked from drivers lugging the dog shi#t out of the engine. When this happens the sensor doesn't show zero movement. Instead it shows the wrong speeds so the ECM is getting incorrect data and isn't able to control the turbo correctly. This leads to the symptoms you mentioned.
