Have you ever noticed that today's newer vehicles lack the responsiveness that came with older throttle cables? Let's face it, no one wants a slow unresponsive car, but this is what we get nowadays, every vehicle sold has some form of throttle delay built into it. Roar Pedal solves this problem by removing response delays from the accelerator pedal allowing you to enjoy a new way of driving. There are 5 modes available. Race Mode, Sport+ Mode, Sport Mode and Eco Mode offer 1~9 sensitivity level. These 36 different parameters allow you to find the perfect feeling of acceleration. Roar Pedal Controller can be installed in 10 minutes or less. It is a complete plug & play system that connects above your gas pedal and works from inside your car, you don’t even need to pop your hood. If you can plug in a lamp, then you can install Roar Pedal Controller, as it requires absolutely no cutting of any wires & does not use the OBDII socket.
