    Eliminate Pedal Lag. If you're driving around town in your Sierra and have noticed a delay in throttle response between the time you step on the gas pedal and accelerate, that is due to the modern Electronic Throttle Control (ETC) Technology, which is also known as Drive-By-Wire. The gas pedal is controlled electronically by sending a signal from the pedal to the ECU, which then sends the signal to the throttle body, which results in that delay. JMS has the perfect solution to get rid of that issue with their PedalMAX Drive By Wire Throttle Enhancement Device. The PedalMAX is designed to eliminate the annoying delay by enhancing the signal between the pedal, ECU and throttle body to make it more sensitive and improve your driving experience.

    Improves Power and Improves Power. The JMS PedalMAX will not only eliminate pedal lag, but it will also enhance the throttle response and improve your horsepower and torque in the low to mid RPM range.

    Maximum Throttle Response. Out of the box, the PedalMAX Throttle Enhancer is preset to provide maximum increase in throttle response. If you find the stock setting to be too aggressive for your driving needs, you can insert the supplied 4-pin RED de-sensitizing plug into the device. The RED de-sensitizing plug will reset throttle response to about 60% of the maximum setting. However, with the optional Remote Throttle Control Knob (part# BX-6999) you can adjust throttle response from 0% to 100% on the fly to match your specific driving style.

    Stackable. The JMS PedalMAX can be stacked or used in conjunction with other aftermarket OBD-II programmers and monitors. It is compatible with products from manufacturers such as SCT, DiabloSport, Edge, Superchips, Bully Dog, and Hypertech.

    Modern Electronics. The PedalMAX Drive By Wire Throttle Enhancement Device features JMS's exclusive state of the art digital technology housed in a proprietary sealed enclosure. The PedalMAX comes complete with plug and play wiring harness using OEM connectors for a quick installation.

    Easy Plug & Play Installation. The PedalMAX Throttle Enhancement Device simply connects to the factory stock pedal position sensor using an OEM style connector with no permanent modifications required. PedalMAX is 100% reversible making it warranty friendly.

    Application. This JMS PedalMAX Drive By Wire Throttle Enhancement Device is designed for use on all 2008-2018 GMC Sierra models.
