Wouldnt you want to make more Torque at a lower RPM in the power band with colder denser air that would require fewer RPM's and fewer injector pulses. Remember for throttle tip in to increase power output the ECU retards timing for a few milliseconds and sprays more fuel to ensure detonation is at a minumum.
