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.

Also can anyone explain the mid power dip on torque? As you can see the top dyno was done October 2016 and the only changes I made was put on Tbatt anti-slip pulley. Hoping to fix my top end slip and get 9psi.

Is it possible it slipping on the SC idler pulley also? I'm using 9lb pulley provided by stillen btw.
