Having a map sensor to adjust fuel trims is useful if you're between high/low altitutde frequently. If you're running off of a purely TPS based map, then you'll run rich at high altitude if you tune at low altitude and lean at low altitude if you tune at high altitude.
It;s not just useful it's a basic necessity of a good fuel injection system. A properly mapped engine controller should run good in all weather/altitude conditions.
yeah, I personally wouldn't run an ITB setup without some kind of MAP compensation.
