Low boost PSI

[Diablo386]

Update on the 386- low boost, lift pump inop-
Truck is demandated, had a mechanic set computer to factory settings and check engine lights came on. Only code that popped up was “VGT actuator abnormal rate reading” or something rather. Vgt was not doing anything when doing the calibration test with Actuator off. So they tried other Actuators that were good and still nothing. All wiring has been checked from Ecm to VGT and was told there are no shorts or breaks anywhere. All wiring is good. Had the truck programmed again and back to it being demandated and truck still running exactly the same. Mechanic checked parameters at idle and actuator is getting 5V supply and turbo is spinning when giving it gas. But at idle Actuator is not opening how it should and turbo is not spinning and can’t hear anything.
Is it possible I have a bad ECM? Everything has been checked I mean everything. From wiring to actuator to turbo to programming...only thing left would be ECM. I bought ECM at a junkyard off a 09 international. Let me know what you guys think about this.
