This boosts line pressure in the trans to give you a firmer harder shift at higher RPM

It changes the shift points and provides a firmer feel during gear changes.

automatic transmissions are made to shift smoothly, sometimes sacrificing power. The performance shift sacrifices smoother shifts for increased power.
