AFAIK, AVC-R actuator stepping motor makes clicking noise, at least it used to in the previous version of their boost controler. Where did you mount your stepping motor/actuator?? It will only click when under boost. Remedy is to mount it as far up in the engine bay as possible, by the radiator or something.
Not sure about the operation, but those damn AVC-Rs are too hard to program correctly, my car boosted differently on back-to-back runs under same conditions.....this was even more evident on a dyno, i NEVER got boost I wanted out of it, when I wanted it.
