Have you checked your actual boost pressure ?
You can just undo the three retaining screws/bolts on the recirc valve diaphragm cover and check the diaphram for splits, cuts or holes and that the spring is ok.
The T.C.V valves can get lazy on them with age as well.

Decent enough video, but physically checking the condition of the re-circ diaphragm is still an ideal way of making sure it's ok.
