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

    This thing is great!

    Made my 2017 Silverado feel like a completely different truck--in a good way! It feels snappier, more powerful and more responsive. Installed in 5 minutes. Definitely worth it.

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

    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.

    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!

    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.

    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!!!
