I never had that happen before. I thought our cars diverts the extra pressure back into the system, as a true blow-off valve which vents to the outside atmosphere, thus hearing a loud swoosh of air?
After you test from the turbo outlets, do you also test from the intake side by removing the air cleaner and attaching air supply to the rubber coupler?

I actually test with the air filter off since it is easier to find leaks with it removed.

I left the air box in. Mine held 1.4 bar, if it didn't hold, your probably gonna hear the leak. I didn't have any so air box stayed in. if you had a loud pop and blow something off, it probably won't even hold pressure very well.
No, what I meant do you connect pressure to the intake at the MAF? The Porsche manual indicates that is where you are supposed to test. That doesn't make sense to me, as you will be forcing air potentially into the crankcase.
