Those boost numbers don't sound right. You should be getting around 18-20 pounds.
I'd pull the intake tubing off the turbo and check the wheel for play or extra oil build-up.
Or you might be having injector problems...

How can i check if i have a bad injector? I will check the wheel on the turbo but what else could cause my problems? Could a weak fuel pump be causing some problems as well?

I have found you can get a better boost reading if your under load. Grab ahold of your neighbor's 15k 5er and see what you have, lol.

Do you have a good connection on the map sensor line where you tied in the boost gauge? I had my little rubber connector go bad (fell apart less than a year old). Amazing the difference when the MAP sees full boost #'s, also a big difference on the gauge.
