    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.

    I read in another response to a question that; 'This will not set any codes or show up when scanning the vehicle, and should not effect your warranty.' My Question; Can it be disconnected if the car needs to go to the dealer, with no issues, reconnected / installed the same way after?

    • This device simply routes and connects to your existing sensor from your accelerator. If you need to remove the device, simply remove the wiring and you are fully back to the original factory harness with no trace of the device being installed.

      Review from JMS PedalMAX Drive By Wire Throttle Enhancement Device w/ Control Knob (08-18 Sierra 1500)

      Big improvement in drivability

      Installed today on 2017 GMC Sierra with 5.3 and noticed instant improvement in response. Both off the line and going down the highway. I bought kit with control knob, but unhooked and left at 100 default. Highly recommended to improve drive by wire issues. Very happy with results.

      JMS PedalMax

      Product is ok. Does give you faster response and don’t have to hold the throttle down to the tires before your truck drops a gear and goes. Sometimes it’s a hit or miss and seems faulty and does not respond all the time.

      Truck woke up!

      Easy install , Was very surprised at the throttle response . complete 180 from what truck ran like prior to install. Took longer to disconnect battery than to install Pedalmax. Plug and play don't get easier than that..

      Came to life!

      Supercharged 6.2, lots of towing power... but not too impressive on street. Until I got this. It brought my truck to life for sure. Have to dial it down to keep tires from breaking loose.

      Review from JMS PedalMAX Drive By Wire Throttle Enhancement Device w/ Control Knob (08-18 Sierra 1500)

      JMS PedalMAX w/ Control Knob.

      Was surprised at how noticeable the difference was once this was installed! However the video used for the description of this product should be corrected, as the guy describing the item clearly says (@ 0:42) that this device plugs into the trucks OBD-II port when in fact it actually plugs into the pedal position sensor. This may cause some confusion. But I would definitely buy this item again as well as recommend it to others.

      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.
