The turbo will function without the APC system. The turbo winds up and pushes the boost up to whatever the wastegate allows, when the boost pressure behind the wastegate overpowers the spring that holds the wastegate closed. If the wastegate is not connected to the turbo, then the spring is also not connected to the wastegate and you get an open system, hence no boost.
The APC system, by way of the APC solenoid, bleeds pressure from behind the wastegate, thus tricking it into allowing more boost.
