    Eliminate Pedal Lag. If you're driving around town in your F-150 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, horsepower and torque in the low to mid RPM range. The PedalMAX is also ideal for eliminating stalling when accelerating from a stop in manual equipped F-150s.

    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 F-150s.

    Application Note. Some early 2009 F-150 models may have a plug that is the same as the 2008 model years. If you do, then you will need this JMS PedalMAX Drive By Wire Throttle Enhancement Device part# PX-5000-0510F.

      Feel the difference, easy install PedalMax

      I got the Pedalmax throttle enhancement device because I wanted a sure way to get more 'go' from my 2004 F-150 5.4. I did the install myself within 15 minutes. The only challenge was finding a place to secure the new wiring out of the way with zip ties. I got a good price from AM with the discount code. I did look elsewhere to compare, but my best deal was with AM. The part is satisfying off the bat, but you will get use to the new feel in time.

      smiling at every green light I take

      This is the easiest to install and most improved performance (immediately felt) I have purchased for my 10 year old f150. Please warn anyone you let drive your vehicle if the setting is left at 100 - throttle is VERY SENSITIVE with immediate response, I love it !!!! Also purchased the adjustment knob, (just to keep the car wash attendant safe).

      Noticeable response

      I received it very quickly and it was a very fast install 5-10 minutes not sure it is just my truck or not but you could definitely feel the difference just wish it was more and if your looking for some real power gains and response add the SCT x4

      Night and day

      2004 Ford F150 Lariat 5,4l-Highly recommend this product.. the acceleration is so much better off the line.. and it works really well with my SCT X4.. I also purchased the variable remote but I pretty much leave it on 100 LOL.. very easy to install literally took 5 minutes 10 minutes if you count deciding where to put it.. I recommend double-sided Gorilla Tape for mounting
