I know nothing about turbo's but, shouldn't your vacuum lines all be connected?

Do you have a Chilton maual? One of those would be very helpful to you.

Leave the boost controller off the car for now, run the line straight to the bottom port of the wastegate and the top port leave open.

What seems to be the problem?

Refer to the bottom of this page for instructions that may be similar to your L26 setup:

Drill and tap the manifold, screw in a fitting. Then there is no guess work

The vacuum lines on a turbo L26 have been covered numerous times. If you search you will find what you are looking for, but you will have better luck going here:
Club Grand Prix! Your online Grand Prix & G8 resource

Some things to search for in the turbo section under topics: vacuum lines, vac lines, l26

You will find what you are looking for.

The only time the car sees vacuum is when it is out of boost...
