Only used for about a month, 100% worth it IMHO. First click completely removes the stock-programmed 'delay' between the pedal and the throttle plate, creating instant throttle response. Higher settings increase the oomph factor so I really only used the first setting, but again utterly worth it, changes the whole driving dynamic of the car. Should have come with this kind of throttle response from the factory. And to be clear, THIS IS NOT THE RACE CHIP TUNER, just the throttle pedal mapper/tuner for driveability - it doesn't increase power or tune the motor in any way.
