I took the WG off and looked around, nothing obvious. I was thinking a new diaphragm but it seems like that would show up all the time.

Wastegate doesn't click. But BOV with worn gaskets does. I suggest disassembling BOV and checking for pieces of (probably worn) gaskets. It might intermittently jam the piston which keeps turbo "recirculating" and thus not boosting.
Thank you for your time,
