Im an amatuer but I concur. You finally have vuccume. This put use/stress on a vaccume line that was not recently under stress like it should be.. The hose stressed out... now you back to square one.

Look for leaks.... Start replacing hoses. Maybe you can bypass some vaccum things and make them non opperational. If all the sudden you get your turbo back then you know that the leak is somewhere in the area you just bypassed.

Another thing... maybe you have a bad ??? that is causing excessive heat or vibration orrr?? to damage a vaccum line. If so this problem probably existed before and is what caused the orginal problems.
