An update - it turns out the cause of the "weak AC" performance on our 2011 Cayenne S was due to (believe it or not) cold air blowing onto the back of the infrared sensor through the slits where the air vent to the left of the PCM attaches into the dash. Here is the Porsche fix:
Instead of detaching the vents and add felt, I wonder if simply blocking the sensor by sticking some insulating layer on it would have similar result.
