I made a long post, but knowing how messy that is to read, I rewrote it:

*What is the vacuum pressure supposed to be and is it a steady pressure or does it vary with RPM?

*I expect the engine mounts to need a steady pressure, but the turbo to need a varying pressure. Am I wrong or is the vacuum somehow modulated?
