I have no idea what kind of boost you should be making but could it be that your wastegate spring is only rated for that ~10 psi. If there are no leaks that's the next thing I'd check.

If the spring is rated for more and is in good condition, could it possibly be that your turbo doesn't flow enough air. I know that's really unlikely but better to know for sure.
