Did you fix the problem? My car was doing the same thing - bucking violently when coming off of full boost/throttle. Ended up being a torn wastegate diaphragm. It was maintaining the correct boost pressure at WOT, but once I lifted the boost would spike and trip the overboost sensor. A quick way to check: Disconnect the wastegate boost signal line at the intercooler and blow into it. if air passes thru you have a leak.
