That's a little low. You should have 14.5 volts at idle.
I know on my power master alternator you have to rev the engine to 2500 before the field windings energize. Maybe it's the same for your pa-performance unit.
Also, you're going to have some voltage drop since the battery is in the trunk. What size wire is used from the alternator to the battery?
I would first have the alternator checked to eliminate that possibility and make sure the wire is heavy enough gauge they used to relocate the battery.
