proper calibration work should definitely include sub zero temperatures.

depends on the individual maps. i would guess that most maps have the same correction factors as factory, which you would hope were done properly by ford in the first place. most chips are just tuning of original maps for increased boost, different cams etc, so do not necessarily have to change any modifiers or correction factors for temperature
