Replaced by N75 valve yesterday and the improvement is very nice.
I was too lazy to log before and after, but I suspected the N75 because I had a Pressure Limit Exceeded code and then some limps on occasion. Also, the turbos would spool up really quickly under part load acceleration. I would have to back off on the throttle to keep the acceleration smooth and linear.
Replaced the N75 and checked the wastegate lines. Partial load and WOT acceleration is MUCH smoother. I forgot how this car's acceleration is supposed to feel. :-)

10-15 psi is all it takes. You can also look at the turbos and watch the wastegates actuate.
The wastegate line is the one that connects to the side of the N75 valve. The other one goes to the compressor outlet. It's okay to put air to it. All you'll hear is air coming out down below at the compressor outlet pipe. That's what should happen. You'd have to plug that hole if you wanted to pressure test that line. Not feasible.
