What exactly does this button do?
change up the valve timing?
sharpen the shifts?

different shift points, higher redline, stays in gear longer before upshifting shifting etc etc... its a different "mode" for the transmission. the actual shifts are the same, and it has nothing to do with the engine or the ecu's control over the engine. just basically a "sport" mode for the trans.
