Link to New JMS FuelMAX for Select GM Vehicles

JMS® recently released their next generation PowerMAX® FuelMAX® product for Gen 5 Camaro, C6 Corvette and Cadillac CTS-V. The new PowerMAX® FuelMAX® V2 Plug and Play Fuel Pump Voltage Booster features exclusive JMS digital technology to provide up to an 85% increase in fuel delivery. The newly released voltage booster is pre-engineered for use on 2010-2015 Camaro, 2008-2013 Corvette and 2008-2015 CTS-V.

The 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. As part of the product’s next evolution, JMS worked with popular late-model GM tuners to develop a specialty product with easier installation and activation. The new Plug and Play design is an industry first and allows the user to now activate the device via the accelerator pedal position sensor, and eliminate the need to use a Hobbs switch or run wiring through the firewall.

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 is the only company to offer user-adjustable voltage ramp in and ramp out rates. This feature allows the user to correct and eliminate fuel pressure spikes that occur when fuel pump voltage is rapidly increased or decreased. You now have maximum control over the voltage ramp-in and ramp-out rate and depending on model, voltage can be controlled via time or boost pressure or it can be controlled via time or monitored voltage, and it’s easy to setup via simple to use knobs and switches.

JMS PowerMAX® FuelMAX® V2 Plug and Play Fuel Pump Voltage Boosters are shipped complete with everything you need for installation. Included in the kits; PowerMAX® FuelMAX V2 device, heavy-duty OEM-grade wiring harnesses, wiring terminals, wire splices and heat shrink, solder, mounting hardware, and 40 amp fuses.
