The O2 sensor doesn't measure air volume but the unburnt fuel in it so it doesn't matter how much air is flowing by it will always meassure the the same thing. The SC injectors are 365cc not 100cc and the ECU ignores the O2 sensor at anything past 1/2 throttle or so, it is only used by the ECU while cruising or during low load conditions.

At least that's how it works on our cars, some newer vehicles which use wide band O2 sensors are continually varying the fuel mixture based on O2 sensor input to the ECU, air temp, etc.
