Mine does the same thing. I would describe it as a lumpy power output. It feels like the turbo goes into overboost and then immediately backs down and again and again. It seems to happen when I'm in a high gear and give it a moderate throttle application. I wonder if unplugging the solenoid connector on the JB as others are doing now would cure this?
