Sounds like the diaphragm in your electronic valve is ripped.
I believe I mentioned this in another post of yours but a boost gauge is NOT an indicator of whether or not you have a leak. Remember turbo systems are FEEDBACK based systems. If the turbo is capable of doing so it will compensate for a minor leak by spinning FASTER and FASTER until it reaches the manifold pressure required to open the wastegate. Even though you are reaching the desired boost, or something close to it, you can still have a leak.
