Electric Boost Solenoid Issues

[97EclipseGSX]

I have an AEM boost solenoid (which is a PWM solenoid) and when its hooked up for some reason the gate seems to surge (opens and closes) when boost is starting to build. It does this full or part throttle with really low boost, normally between 0 and 3 PSI, sometimes more. I'm baffled as to why it does this. The duty cycle is set at 25% which should be around 10 pounds with the spring I have.

When the solenoid is out of the equation and the gate is running off of the spring, like # 5, everything works as expected. Also works fine when the solenoid is unplugged, which means the solenoid acts as a line causing it to run off the spring like in #5.

I created a picture of a few different ways I could think that the solenoid can be hooked up. Mine is currently hooked up like number 2.

Has anyone run into this before?
Which diagram would you use or have you used that works?

Thanks for any help

Well if you want to run both nipples hooked up I would try it this why. Run manifold boost source to the bottom nipple. Then pre turbo boost source to the soloniod's COM's port, then the NC port to the top nipple.

It does make more sense to run the lower port to manifold pressure if I'm gonna run both lines to a pressure source. So, I changed the diagram to reflect that suggestion. Thanks.

But its not that I want to run it a certain way. I only want it to stop popping open and closed like it is.
