    Say Goodbye to Pedal Lag. Get an instant pedal response on your GMC Sierra with the advanced JMS PedalMAX Throttle Enhancement Device. When driving 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 this 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. 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, this kit also includes a Remote Throttle Control Knob, so you can adjust your 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-and-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 with Remote Adjustment Knob is designed for use on all 2008-2018 GMC Sierra 1500 models.

        5 Top Rated Questions

        Will this device help with the deceleration the same way as it help with the acceleration. When I let off my pedal there seems to be a lag time.

        While this will not increase gas MPG, will it decrease MPG significantly?

        • You may see a slight decrease in MPG, but it can honestly depend on how the vehicle is driven.

        I have a 2009 sierra with 5.3 the truck is also a flex fuel vehicle will this affect anything will it still work

        • This PedalMax product is compatible with the Sierra 5.3L Flex Fuel and will not affect the performance of your truck.

        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.

            I don’t know why or how, but this device literally screwed up the ecu in my truck! I just bought this truck too and it’s already in a shop getting fixed. DO NOT BUY THIS JUNK!

            Good response

            This item did what it says it'll do. However, my trucks computer had some issues with this. My check engine light would come on due to loss of traction control and the engine would put itself in a reduced power state. I would then have to unhook the Pedalmax to reset the computer. I never hooked it back up cause I dont want to run the risk of jacking my trucks computer up.

            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..

            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.

            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.
