By reducing pedal lag, the Throttle Sensitivity Booster forces your performance curve to occur sooner, achieving quicker engine response and a "fly back in your seat" feeling. The plug-and-play module easily installs in minutes using factory connections and is adjustable with push button on-the-fly control to boost throttle signals by 50%, 75%, 100% and even 400%. There is also a "Valet" mode that decreases the throttle signal by 50% for when you lend your vehicle out. Available for most gasoline or diesel powered North American made pick-ups, SUV's, Jeeps, cars and vans.
