Check the wastegate arm, make sure it is attached to the accuator arm on the turbo. If its disconnected, you wont see any boost at all, maybe 1psi max. Have you done a boost leak test yet?

basically you hook a regulated boost source up to the inlet of your turbo and see if there are any leaks at any of the couplers on your charge pipes, intake manifold, etc..
My guess is that the wastegate actuator took a shit. The diaphrams on them fail after a while and give the same symptoms that you are describing.
