JMS has spent over 25 years building a reputation in the Ford and Mopar performance communities as a brand that makes meaningful upgrades accessible to everyday enthusiasts. Founded in 1995 and based in North Carolina, JMS specializes in electronic performance products that deliver real results without requiring professional installation or expensive tuning equipment. The brand's signature product, the PedalMAX drive-by-wire throttle sensitivity controller, has become one of the most popular bolt-on upgrades for Ford Mustang, F-150, Bronco, and Dodge Challenger/Charger owners — improving throttle response and eliminating drive-by-wire lag in a plug-and-play format that requires no tools and no programming.

For Ford and Mopar enthusiasts who want genuine results and the confidence of buying from a brand with a proven track record, JMS is a straightforward, reliable choice.
