JMS Chip & Performance Releases PowerMAX FuelMAX V2

Boosted vehicles require lots of fuel; often a factory fuel pump assembly isn’t up to the task as configured on the assembly line. But a product like JMS Chip & Performance‘s PowerMAX Fuel Pump Booster can pump up the voltage and the pump’s output in the process. Check out the specifics on its operation below.

Official Release/Features:

JMS Chip & Performance recently launched the next evolution of their popular PowerMAX FuelMAX product. 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. The newly revised voltage booster is pre-engineered for use on most GM and Chevrolet vehicles: Camaro SS and ZL1, Corvette Z06 and ZR1, Chevy SS, Trailblazer SS, Silverado truck, Pontiac GTO and G8, and select Holden cars.

The JMS PowerMAX FuelMAX V2 provides the highest continuous voltage and amperage output without noise, and is available in true 40-amp and 80-amp input fuse configurations. Another industry first includes the ability to choose how to enable the units voltage-boosting output. Two versions are available; one version activates the device via a built-in internal boost pressure sensor (1-29psi), and the other activates the boosted output via a Ground or a monitored 1-5-volt external signal (MAP, TPS or PPS sensor signal). The new device activation options allow you to choose the device that works best for your specific vehicle installation.

The recently updated PowerMAX FuelMAX V2 has an all new proprietary enclosure and industrial heat-sink, featuring 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 over-ride control knob that adjusts voltage on the fly.

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 harness, 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.
