You're right. It is weird
I don't know. Maybe check your air charge tubes going to the intercooler. Maybe the clamps are loose. You would think you would be loosing power if that were the case though because you would be loosing turbo boost if they were leaking. If it were a gas engine, I would almost say that you have a vacuum leak. Some of the techs might chime in on this later. Anybody else have any ideas
