Installation Instructions

Part Number:


The PedalMAX by JMS Performance is engineered to safely improve your vehicle’s throttle response and driving characteristics. Installation is simple, quick and easy. In just a few short minutes, you’ll be able to take advantage of a noticeable improvement in throttle performance. Today’s vehicles are equipped with “drive-by-wire” electronic throttles. Unfortunately, poor throttle response and pedal lag are very common, especially in performance and racing applications. The PedalMAX plugs in-line between your vehicle’s pedal position sensor and vehicle harness. PedalMAX will increase the torque and responsiveness of the OEM drive-by-wire throttle assembly, and with the ability to customize your pedal’s responsiveness, you finally have complete control over vehicle’s acceleration.
