Anyone have any experience with the original greddy profec-b controller?

[Bronze MFP]

With carl h's help again we hooked up my greddy profec-b controller the other night. It started off with a nice overboost problem that was caused by using hoses that were too small going from the compressor to the control box and back to the actuator. I bought larger hose and hooked everything back up like it should be. Base boost holds fine at the stock levels again, but when i turn on and try to use the controller, nothing happens. Boost never rises above stock no matter how high i turn the knobs. I'm guessing the solenoid box is shot. Does anyone have any experience fixing one, or know where i can get a new or working one?
