1990 TT Electronic boost controller issues

[1990TTZ]

I've been running my Z32 at .95kg cm^2
I've notice I've had to turn up my duty cycle on my apexi avcr recently to keep it at desired boost level.

The other day i wanted to run on my B setting at 1.10kg cm^2 it will only pull maybe .07 kgcm^2 more
Than on A setting it's set on a duty cycle 90% all the way through the rpm range on the controller.

Yesterday i cleaned my air filters and ordered a boost leak tester since I can't find my old one.
Checked all my clamps and didn't see any thing out the ordinary.

Here's my real question how to check the avcr boost soleniod and is it supposed to receive power and ground from the avcr. Because my solenoid I can easily blow trough it when un plugged or plugged in with the car running the soleniod flows free through.
I checked power source from the head unit to the soleniod and only have power on one pin and nothing on the other. When I plug the soleniod in theres power on both wire like it just going straight through the soleniod. But when testing the soleniod with a power probe I can hear it click and once it is engaged I cannot blow through it any help is greatly appreciated.

Thanks

BTW, multiple posts of the same question not only limits the help you may get, but also clogs the page with useless posts so your other post has been deleted.

Kind of a tough one here as it seems like an issue that would be specific to your setup/equipment, and not something that anyone who doesn't use your equipment/setup would know much about, most likely (I surely don't from the info given).
My advice would be to contact or look up any specific info about your avcr solenoid (website, product info book?) and wiring diagrams/requirements and start there, making sure your connections are correct as it seems there is a ground issue perhaps. Deletes are also a minor concern as sometimes deleted systems are still looped in the wiring and issues can occur, such as the cam sensor that went out in my G35 and caused the rear braking system to be activated randomly and ruined by that trouble code signal, somehow. Perhaps your avcr signal is getting corrupted somehow?

Hope this helps, and that anyone else with more detailed knowledge or info chimes in!
