Hi Guy, from the topic i have the similar issue.
My N75, Wastegate and BOV all replaced. Previous my boost is uncontrollable and hit 2bar and power cut.
After fixing it now is target at 1.8bar but it will still cut.
ECU is tune and tuner mention is my HW issue. Since i already replace the part. I not sure where else to find.

Changed my LPFP.. Now holding at 5bar at WOT. We might found out the issue.
High chance is DSG limiting the Torque request.
