Default utec - stock boost solenoid

My stock ECU will no longer drive the stock solenoid to control the boost. I haven't gotten a cable from the engine bay into the cabin to check the voltage while operating, but it's pretty suspicious to me.

What is the likelihood that the UTEC will be able to drive the solenoid?

I know the solenoid is not dead because I can activate it manually with a battery. Is it possible that the solenoid can no longer pass the sufficient CFM to hold higher boost pressures?

The same thing happened to me so I just built a Manual Boost Controller and added the ABC bleeder that comes with the UTEC. Leave the bleeder all the way open and adjust the boost with the MBC. It only cost me $12 to make the boost controller. Hope that helps.
