Be worth checking the vacuum at the vacuum pump see what vacuum there is with everything disconnected ie servo . i would of thought they would of given you a new turbo as the activator are matched , the later models have a position sensor on the activator tells the ecu the position of activator
The vacuum regulating valve is a pulse width modulated affair, it can become clogged especially on the atmospheric pressure relief which should originate at the clean side of the air filter box.

Thank you for your input.
This turbo and actuator is not that clever.
The ECU switches on the vacuum and watches the boost.

The actuator was 100% brand new with the turbo.

Parts do fail in early life, the diaphragm is rubberized fabric which could have had a low cycle fatigue failure.
@@keithjurena9319 it never worked from new.
