PedalMAX® is the industry's first and only complete solution designed to improve throttle response and driving characteristics on all 2005 and newer Ford vehicles, 2008 and newer GM vehicles, and 2007 and newer Dodge/Chrysler/Jeep vehicles. PedalMAX is easy to install, and plugs in-line between the vehicle's throttle position sensor and vehicle harness, providing a huge improvement in throttle performance and responsiveness.


All vehicles built today are equipped with a "drive-by-wire" electronic throttle. One of the biggest consumer complaints has been poor throttle response and throttle lag, especially in performance or racing applications. JMS PedalMAX® is designed to improve the throttle response on almost any common car, truck or SUV.


This first of its kind digital microprocessor-controlled device dramatically improves throttle reaction and acceleration. PedalMAX® also reduces turbo lag and improves low and mid-range performance on small displacement turbo vehicles or large turbo-diesel trucks, and makes your vehicle fun to drive again.


Other extended PedalMAX® benefits include, seamless and warranty-friendly installation, advanced user throttle control via the optional control knob, and the device requires no aftermarket OBD-II tuning or programming. This innovative new product can also be stacked or used in conjunction with common aftermarket OBD-II programmers and monitors such as: SCT, Bully Dog, Diablosport, Hypertech, Superchips, Edge and other manufacturers’ products.


PedalMAX® features exclusive JMS digital technology housed in a proprietary sealed enclosure, and comes complete with plug and play wiring harness using OEM connectors for quick installation. The complete system is designed to be used on many different gas or diesel cars, trucks and SUVs regardless of engine size and will improve the driving experience significantly while adding improved low and mid-range performance.
