The APR Throttle Booster instantly transforms how your vehicle feels by customizing how quickly your throttle or accelerator pedal works. Plug it in, and either uses the wireless controller or smartphone app to set or customize how the pedal feels. Most people don't like how their throttle pedal feels, and while tuning can help eliminate lag, everyone has a different opinion about how it should feel. This device lets you set it exactly the way you want and allows you to switch between profiles quickly. Set it to stock, sport, extreme, and eco modes easily. Best of all, it's a quick plug-and-play device that can be removed anytime.
