VW used that engine in many Audis and Seats, including the TT and A4, and had it producing 40-50 percent more hp and torque stock on some of those platforms. The GTi's version made just below 180hp stock -- yet had the same drivetrains and internals. An ECU flash instantly produced 35-40 more hp and @ 50 ft-lbs. All one needed to do to eat Boxsters for lunch was mildly upgrade the suspension.

Exactly
The MkV TDI's were coming spec'd with Luk and/or Sachs DMF/Clutch units that were so badly underspec'd by VW that the DMF's were heating up, warping then cracking due to metal fatigue and eventually they would break and when that happened it was like a grenade went off in the transmission housing turning a 1k job into a 6k clutch/transmission replacement
Most people replaced them right off with a solid flywheel/clutch combo (VR6/G60 combo) and never looked back
I'm admittedly a bit skeptical of anything with a DMF in it.....give me a solid flywheel
