I'm well aware, I'm a dealer for Geoff . I actually work very closely with him to develop his Tdi performance grinds. He's a stand up guy for sure.Colt cams makes a replacement cam for those engines.

Known Problems??
The balance unit is easily replaced with the standard oil pump setup from the jetta's/golf's though for only $200 in parts. The vibration increase is minimal at absolute most. Most of my customers can't tell.As mat said the balance shaft modules go bad and the upgraded gear driven unit is a $2500 fix (P&L).
Engine mounts commonly go, and the auto transmission is barely up to the task.
