These days vehicles are no longer powered with the old school throttle cable that gave you a linear relation between your foot and the throttle body. Everything is now powered by electronics and your car’s computer (ECU), which manufacturers make with a "one size fits all" process. The electronic throttle does not provide the same performance as it creates a lag from your initial accelerator push. Pedal Commander gives you the ability to eliminate the response delay from your electronic accelerator (gas pedal), allowing your engine to respond faster. As a result, your gas pedal becomes more sensitive for a sportier or an old school feel. You can also make it less sensitive if your main goal is to increase fuel economy.
