How do you know how much boost you are running if you have an adjustible wastegate, and how do you adjust it
You monitor it via your aftermarket boost gauge (a MUST HAVE).
To raise boost, you shorten the rod by tightening it. To lower boost you lengthen the rod by loosening it.

The above link may help to understand as well...
Who makes the best boost controller (best bang for the buck) for the 1986-87 turbo Buick.
