    Review & Install Video

    Put a Spring in Your Truck's Step. As powerful as they look on paper, today's engines often don't feel as responsive as the numbers would suggest. That initial split-second hesitation after throttle tip-in can feel like an eternity. It can make a 420-horsepower monster seem like a pushcart under the wrong conditions. To eliminate this annoying delay JMS created their PedalMAX Electronic Throttle Enhancement Device.

    Take Up the Slack with PedalMAX. Using your truck's own drive-by-wire circuitry, the JMS PedalMAX eliminates the lag. It makes your engine's power available instantaneously. It improves automatic transmission shifting, and eliminates stalling with manual transmissions. Overall, it hones your engine's response to a sharper edge. Included in this package is the JMS remote control knob, which allows you to adjust your throttle response on-the-go.

    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 to 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 included Remote Throttle Control Knob you can adjust throttle response from zero to maximum or anywhere in between 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 such as: SCT, Diablosport, Hypertech, Superchips, Bully Dog, and Edge as well as JMS' own BoostMAX Performance Booster.

    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.

    Quick and Simple Installation. PedalMAX connects to the factory stock pedal position sensor using an OEM style connector with no permanent modifications required. There's no ECM reprogramming required and it's 50-state emissions legal. PedalMAX is 100% reversible making it warranty friendly.

    Application. This JMS PedalMAX Drive By Wire Throttle Enhancement Device w/ Control Knob is designed for use on all 2008-2018 Chevrolet Silverado models.

    Will it void warranty and do it add miles per gallon


    Void warranty? Will this show up on a dealer scan? How does this exactly work (does it reprogram computer)?

      JMS PedalMax

      It took me less then 5 minutes to install the pedalmax. It works great. I get much better throttle response. It has made a positive improvement. I would recommend this product.
