    Features & Details

    • Eliminates Throttle Lag
    • Improves Vehicle Acceleration
    • Easy Plug & Play Installation
    • Stackable with Common Aftermarket OBD-II Programmers
    • Fits 2008-2018 Chevy Silverados
    Give it Gas, and Make It Snappy. Today's truck engines are enormously powerful, but thanks to a lag programmed into the latest drive-by-wire systems, they often don't feel that way. A split-second delay after throttle tip-in can make a road-burning V8 feel like a lawnmower engine while driving around town. To eliminate this annoying delay JMS created their PedalMAX Electronic Throttle Enhancement Device.

    PedalMAX Eliminates the Slack. The great advantage of drive-by-wire is how factors like throttle response can be shaped for individual applications, drivers, and situations. The JMS PedalMAX is a quick and easy-to-install mod that leverages drive-by-wire. In an instant, it will correct the hesitation making your truck feel sluggish. It improves the shift feel of automatic transmissions, and makes it a lot harder to stall the engine in a manual transmission truck.

    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 optional Remote Throttle Control Knob (part# BX-6999) 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 Easy 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 is designed for use on all 2008-2018 Chevrolet Silverado models.

    Was wondering if the " optional 12 volt wire" has to be connected? My kit differs in looks, like its a newer design. Instructions are vague on it. If so, if it has to be, that makes the "plug and play" a little bit more involved. Thanks in advance for clarification. I have the JMS-PX-5000-1015GMT 1 answer
    I have a diablo intune i3 if I get this will I have to retune my vehicle? And does this have a female obd2 built into the opposite side? So if its plugged in will I be able to plug in a programmer? Or do I have to unplug one and plug in the other? 1 answer

      Throttle enhancement

      Was a quick and easy install, only tool about 15 min and most of that time was getting the power wire run. Now when I hit the gas it actually goes. Definitely wouldn't turn it all the way up to 100 at first, start at 50 and gradually turn it up as you get used to it.

      Review from JMS PedalMAX Drive By Wire Throttle Enhancement Device (08-18 Silverado 1500)

      Buy this first!

      The difference between the stock throttle response and the JMS PedalMax response is night and day. All I can say is buy this first, before any other additions. I added a Cat Back Exhaust, a Diablosport Predator tune and a Cold Air Intake. The JMS PedalMax is the most noticeable improvement of all. Feels like a totally different truck now. Great purchase!

      i ordered this part for the throttle lag i had in my 2011 silverado. I installed it and it got rid of the lag. I am very happy with the part. I recommend this part for the people that are having the lag issue..

      Overpriced

      This item should be 100 or less . I got the new style that you have to run a wire to the battery and all that for just a little difference . is overpriced for what it does.

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

      Great product!!

      I would definitely recommend this product to anyone who wants to get immediate response from hitting the gas. I have a 2014 GMC Black Widow with a 2.5L supercharger and I installed this product and it came to live at a touch of the pedal. Overall great for the money and time put in!!!
