      Video Review & Installation

      What's going on, guys? I'm Alex from with my quick review of the JMS PedalMAX Drive By Wire Throttle Enhancement Device, fitting your 2005 through 2010 Mustang. So, in this video, I'm gonna give a quick breakdown of what you can expect in terms of performance, what you should expect to be spending. And then last but not least, we're gonna hit the installation, which right off the bat, I'm gonna be giving a very easy 1 out of 3 wrenches on the difficulty meter, and you should have this on your Mustang in about 30 minutes or less.So, if you're the 2005 through 2010 Mustang owner and you're looking to make a great improvement in your Mustang's throttle response, but you're not too into the idea of picking up a custom handheld tune, this is definitely gonna be the product for you. So, the team over at JMS saw a little bit of weak spot in terms of the throttle sensitivity, as well as how well it responds in the '05 through '10 Mustangs, and they thought that this could definitely be improved upon.So, giving you a quick refresh, some of the older Mustangs are gonna be a cable-driven style in comparison to the newer drive by wire system, but still, it's a little bit on the lagging side. So, the guys over at JMS found that the '05 through '10 Mustang, despite having a drive by wire system, still lagged a little bit and was kind of reminiscent of what you might find on either a Fox Body or a New Edge Mustang, which is cable driven. So, the guys over at JMS saw this void and they brought the PedalMAX to market with the Mustang owner in mind that's looking to greatly improve their throttle response, make it that much more crisp, and a little bit more lively.Now, this is not something that's gonna be giving your Mustang horsepower and torque. I definitely wanna get that out there, first and foremost. But, this is gonna be great for the Mustang owner that wants to keep their warranty in check, if you do have an extended warranty on your '05 through '10.So, with the electronic throttle control technology, or drive by wire setup, what you're gonna notice is that there is a huge lag between the point where you put your foot on the gas and when the blade of your throttle body opens up. So, a drive by wire system is gonna monitor the position of the gas pedal in terms of how open or closed your throttle's gonna need to be. So with the JMS PedalMAX, this is going to give you that much more crisp and clear throttle response.So, right out of the box, this is gonna be set at the most aggressive setting, but I do wanna mention that JMS does have a separate controller here which will give you the ability to tailor this to your driving style.So, in terms of the construction and what you're gonna be getting in the kit here, guys, we're gonna see that all their software's gonna be right in this kit right here, as well as coming supplied with an OE style harness, which is going to make the installation virtually painless.So, in terms of the pricing here, you should expect to be spending right around 300 bucks for this kit. And I wanna brutally honest here. I've driven this unit on about three different cars right now, and while it didn't honestly blow my socks off in terms of horsepower and torque, the throttle response was definitely there. So, for the money here, for an extra 100 bucks, I honestly think a full-blown custom tune might be a little bit of a better buy, but if you're an extended warranty owner and you're looking to keep that in check, this is definitely gonna be a perfect option for you.So, again, while this product was brought out for the Mustang owner in mind that's looking to retain their factory warranty, if you still have it, as well as giving you a decent bump in throttle response, if you're gonna be looking for horsepower and torque, I would definitely suggest getting into a custom handheld tuner as, again, the difference in price here is only going to be around 100 bucks, plus it's gonna give you the ability to monitor a bunch of different parameters, as well as clear and scan engine codes.So, taking a quick look at the installation, just like I had said at the beginning of the video, you're gonna be looking at a very easy 1 out of 3 wrenches on the difficulty meter, and about 15 to 30 minutes to get this onto your car. Now, the ease of installation here is definitely gonna be another selling point for me, as there's really no guesswork to this. You are gonna be connecting this, pulling your negative battery terminal off, and then pulling your wire harness out from behind your gas pedal, and then you're good to go. It honestly does not get any easier than that.All right, so just to wrap things up here, some final thoughts. If you're the Mustang owner that's looking to improve your throttle response drastically, but you're not too into the idea of picking up a custom handheld tuner, this is definitely gonna be the option for you, not only based on the fact that this is gonna install in a heartbeat, but it's gonna make your daily commute that much more enjoyable.So, that's my quick review and breakdown of the JMS PedalMAX Drive By Wire Throttle Enhancement Device, fitting your 2005 through 2010 Mustang, available right here at

      Eliminates Pedal Lag. If you have ever made a left turn across oncoming traffic, you have most likely noticed a delay in throttle response that has left you wondering if you are going to make it across with out getting hit. This pedal lag is caused by the drive by wire accelerator found on the 2005-2010 S197 Mustangs. On previous generation Mustangs the gas pedal was connected to a physical cable that ran directly to the throttle body and provided immediate response. However, on modern Mustangs the gas pedal is controlled electronically, like a dimmer switch, which has to send the input signal from the pedal to the ECU, which then sends the signal to the throttle body, causing a momentary delay in response. JMS created their PedalMAX Electronic Throttle Enhancement Device to eliminate this annoying delay and improve your driving experience.

      Eliminates Stalling and Improves Power. The JMS PedalMAX will not only eliminate pedal lag, but it will also enhance throttle response, horse power 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 Mustangs, a notorious issue for the Shelby GT500's.

      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.

      Easy Plug & Play Installation. The PedalMAX Throttle Enhancer 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 2005-2010 Mustangs including the V6, GT, Bullitt and Shelby GT500 models.
