When I was looking for a boost leak I made a leak tester and pressurized the system up to 8psi and both of the sensors read the same (engine not running) during the test. The leak showed up around 3psi if I remember correctly. If you have an aircompressor and a good pressure regulator I'll be glad to loan you my tester that I made.
Top, do you have any words of wisdom that you can share?

Yes I have GTR map sensors. But for some reason they still over range and the map code still came back. So I got my tuner to disable that map code.
I don't think I have a vacuum leak I've checked all the lines. I could do a vacuum test as you mention and find out.
I'm using greddy infometer touch boost sensor and gauge. It's digital and connects via OBT-2 live. The monitor can record hi peak of the boost. The weird thing is, it says I hit 9.3 psi at 7600rpm. But during dyno it only shows 7.5-7.7psi max and my tuner could see on top end the power when the car start to slip or not get anymore psi.
