Pedal Commander is the world’s best-selling throttle response controller. It connects to the drive-by-wire gas pedal using a quality harness with OEM plugs, intercepting and remapping the factory signal to eliminate throttle lag. With four driving modes—Eco, City, Sport, and Sport+—and nine adjustment levels in each, you get total control over your Chevrolet Impala’s throttle response. Experience instant acceleration, smoother power delivery, and a more engaging drive with zero pedal delay.
