Check all the turbo hoses and the Vaccum line to the Waste gate valve.If everything is good the waste gate valve might be bad.

RE: lack of boost /low boost

When my buddy's A4 turbo started losing boost we replaced all his vacuum lines and hoses. It fixed the problem immediately. As for my Subaru 2.0L turbo, I found that my throttle linkage was not allowing full throttle, therefore, it never spooled up all the way. I had a special bracket welded in the help support the cable...now I have 15.6 lbs of boost as compared to the stock 8 lbs!
