If you are looking to improve your overall driving enjoyment or improve your gas mileage, you need Pedal Commander. Most newer cars are manufactured with Electronic Throttle Control (ETC). This means your acceleration is no longer powered with the old school throttle cable that gave you a linear relation between your foot and the throttle body, but now everything is powered by electronics and your car’s computer (ECU). The electronic throttle does not provide the same performance as it creates a lag from your initial accelerator push.
