Like Lonestsr said. You need to have a completely free flowing hollow pipe through the exhaust system. Pull the pipe off and away from the turbo and take it for a spin. See if your problem goes away. You'll them know if this is causing your problems.

If it's not causing your problems it will still cause long term problems like Lonestar said.

Did someone from this site do your ECM demandate? If not you need to have it checked. 300,000 miles of wrong programming will absolutely damage the internals of the engine and cause this problem and many many more.
