Overboosted

Actual vs specified should follow each other. It will spike above then it should come back and trace it

With 180k on the clock it was past its sell by date  :sad:

Sticky vanes is the most likely cause

When you replace the turbo make sure you clean the intercooler out; renew the boost pipes (if not already done) and make sure the actuator is set up properly
