Why would you need to test vacuum on a ST?

There should be no vacuum at the wastegates. Only way would be intake manifold if you need vacuum.

Looking to test how much vacuum my car has for PCV.wanted to make sure my car isn't pulling too much or am pulling correct amount of vacuum.not sure if it's important for single turbo cars but hearing people having issues with either pulling too much vacuum or not enough so...

You'd check through the intake manifold to see how much vacuum you have.

Is your car smoking or burning oil quickly? If not, then you have nothing to worry about.

That thing can just be unplugged and thrown out, it wont even throw a code. I think it just heats up whatever passes through for emission purposes. I cant be quoted on that though
