it sounds to me like the engine is boost cutting, this happens when the boost pressure is to high the ecu closes the throttle for a split second causing a violent jult. I would try a new boost pressure control valve and check the air lines connected to it for leaks or splits. Good luck let me know how you get on. MTech
