The APC control unit is a pretty simple and straight forward component. If you're having problems with your boost and APC system, look elsewhere first. The three signal sources for the APC system (knock sensor, pressure sensor and rpm) have a wire running from each one to the box itself. Those connections and the wiring are often suspect, especially the knock and pressure sensors. The pressure sensor is also known to die internally, and the symptom of that happening is a constantly chattering APC solenoid on top of the radiator.
Are you having boost problems? Solenoid is chattering non-stop?
