Insite will let you cycle the actuator so I would try that and listen for air leaks as well as making sure the turbo is actuating all the way. Its almost like the turbo builds pressure and the pressure actuating the actuator is lost putting the turbo back into its original position.

We did a turbo test through insight and the actuator and turbo passed. But assuming you are correct, it does not explain the large and rapid boost leak ( which we can't identify where it's coming from)
