It also doubles as a valet mode to keep a driver (or even your newly licensed teenager) from being able to accelerate above a certain rate. Many of our customers say that city mode allows the vehicle to accelerate as it should have from the factory. It gives you the response of an &#034;old school&#034; throttle cable, with a 1:1 pedal-to-throttle acceleration ratio. Gives any vehicle the response and acceleration of a race car, allowing you to get up and go when you need to without waiting for the ECU to catch up to your foot. Perfect for spirited driving or on a race track. Please use with caution!
