Most modern vehicles use wires with current running through them to the throttle pedal rather than strands of wire that create a cable physically connected to the throttle body. This was done to simplify the engine bay and eliminate the need for cable routing. When you consider that your engine is computer controlled anyway, this starts to make sense. But when you mash the pedal and nothing happens, you might start to second-guess your drive-by-wire throttle. By adding a computer between your foot and the throttle valve, OEM manufacturers have the ability to minimize tire spin and increase mileage by limiting how quickly the acceleration can be applied.
That is all well and good for the family minivan, but when we need to climb a loose hill or pull out in traffic we want all available power right now. Our 2014 Ram 3500 had a bad habit of being slow to respond, particularly when we got off the throttle and then back on it again quickly. Fortunately BD Diesel Performance offers an affordable solution that allows you to increase the responsiveness of your pedal with simple plug-and-play installation. And despite the company name, BD’s Throttle Sensitivity Booster is available not only for Chevy, Dodge, and Ford diesel trucks but also gas-powered cars and trucks, including the Jeep Wrangler. While the Throttle Sensitivity Booster is not a replacement for the appropriate axle gears in a lifted Wrangler with oversized tires, it does noticeably improve responsiveness and installs in just minutes. Maybe computerized controls aren’t so bad after all.
