The JMS Chip FuelMAX EZ is a fuel pump voltage booster designed to support increased horsepower in 2020-2022 Mustang Shelby GT500 models.

This unit is specifically engineered for 2020-2022 Shelby GT500 models and is not compatible with other vehicle configurations. The system utilizes a plug-and-play wiring harness for simple installation, typically requiring approximately 30 minutes to complete with no need to run additional wiring or modify the vehicle's factory electrical system.
