Ive seen a R32 tunerwebsite saying that the DSG box is fine with 425 BHP and 400NM of torques.
The guys at awsome were running 350 bhp + on there MKV (not sure how much torque) with standard DSG box too.
I'm Sure it will take the extra 30bhp and torques
you can get uprated DSG clutches but they ain't cheap....
