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.
