I have the curves in another thread, which I will try to find in this forum. That thread is: BAE Install Dyno Data

I have since changed the old wastegate to a new Tial Sport with 5.8 PSI spring.
The pop off valve is actually a return valve back to the inlet side of the turbo, vacuum controlled. I believe it is an OEM Audi valve. I believe you have a good idea about that, maybe I am bleeding of boost, so I will plug it this weekend and see if I get any improvement with it plugged.
