Because ITB's have poor vacuum as the throttle opens, it's difficult for the ECU to calculate load in Speed-Density mode. What ITB mode does is it tells the ECU to switch from Speed-Density to Alpha-N when the MAP rises above a certain percentage of barometric pressure and you are also above a certain throttle percentage. This allows it sense load with MAP at low throttle openings for good drivability but still be drivable at large throttle openings when MAP is unreliable.
