Use a vacuum tester. Get one from ebay.

For turbo boost??? maybe not..

A dial type tyre pressure guage works well if you remove the holding valve.

Had a prob with my e class 300td traced to a vacume elbow cracked connected to the headlight adjusters i had no vacume hold , Simple check pull the vac pipe of the wastgate valve suck on it with your mouth and then cover with your tongue if your tongue is held to the end you have no vac loss , you may have to lengthen the pipe with another bit to reach , the elbow on mine was behind and below the ecu box , If you have no vac hold get someone else to then blow on the pipe and listen for the leak . simple and worked for me !

Where the boost MAP sensor sits on the inner wing. T into the small pipe that comes off the manifold.

I ment use a vacuum tester to test the vacuum pipes. Not boost pressure.
