not being able to build boost would stem from either the wastegate door being stuck open, which isnt the wastegate being bad, its due to carbon build up, or a hole in the exhaust manifold. the overboosting is a good sign if you dont have a manual boost controller. not quite sure what the test was again though
 
Take off the vacuum line for the wastegate and blow air into it, if you can it's bad, if you can't it should be good.
