Official Release:

JMS Chip & Performance is first to market with a complete plug & play high-horsepower fuel pump solution for the new 2015 Ford Mustang. The new PowerMAX FuelMAX V2 Fuel Pump Voltage Booster features exclusive JMS digital technology and is designed to provide up to an 85% increase in fuel delivery. FuelMAX has been pre-engineered for use on 2015 Ford Mustang GT and V6. Customers have reliably made over 925 rwhp using the stock fuel pump and the PowerMAX FuelMAX.

The JMS PowerMAX FuelMAX V2 provides the highest continuous voltage and, amperage output, and is available in 40-amp single and 80-amp dual input fuse configurations. Two versions are available: one version activates via a built-in internal boost pressure sensor (1-29psi), and the other version activates the boosted voltage output via a Ground or a monitored 1-5-volt external signal (MAP, TPS or PPS sensor signal). These activation options allow you to choose the device that works best for your specific vehicle installation.

JMS was the first company to produce a plug and play fuel pump voltage booster for the Mustang, and their new PowerMAX V2 for 2015 Mustang carries that innovation even further. For the ultimate in easy installation, owners can choose to utilize the new Pedal Position Sensor plug and play option that activates the device by monitoring the accelerator position. The Pedal Position activation eliminates running wires through the engine firewall altogether.

PowerMAX FuelMAX V2 features a proprietary industrial heat-sink enclosure and is equipped with 10 gauge heavy-duty wiring and either 40 or 80 amp fuses, along with a host of new and innovative features to further improve the user experience. The maximum output voltage range is user selectable (18.5 or 22 volts) and is controlled by a knob in the faceplate, or via the optional in-cabin remote over-ride control knob that adjusts voltage on the fly.

JMS is also the only company to offer user-adjustable voltage ramp-in and ramp-out rates, a feature that allows the user to correct and eliminate fuel pressure spikes occurring when voltage is rapidly increased or decreased. You have maximum control over voltage ramp-in and ramp-out rates, which can be controlled via time, boost pressure, or monitored voltage with easy setup via simple knobs and switches.

JMS FuelMAX V2 Fuel Pump Voltage Booster Kits are shipped complete with everything you need for installation. Included in the kits; PowerMAX FuelMAX V2 device, heavy-duty OEM-grade wiring harnesses, user adjustable Hobbs pressure switch, 1/8″ NPT adaptor fitting, wiring terminals, wire splices and heat shrink, solder, vacuum line and tees, mounting hardware, and 40 amp fuses. Internal boost kits include vacuum line, and the plug and play pedal position sensor kits include a pre-engineered harness with OEM-type connectors.
