Show original supplier description
Designed for 2015 and newer Ford Mustang models (GT, V6, and 2.3L EcoBoost), the PowerMAX features a 44 Amp rating and a voltage range of 14.4-22V. It seamlessly integrates with your vehicle's electrical system by plugging directly into the fuel pump's +12V DC feed wire. The system is compatible with both 12V and 16V battery configurations. Installation is simplified with plug-and-play wiring harnesses, including a dedicated pedal harness for activation. The unit can be triggered via the accelerator pedal position sensor, a ground signal, or a 0-5V external sensor, offering flexibility in setup. To prevent fuel pressure spikes, the PowerMAX includes adjustable Voltage Ramp In/Out times and a Green Status LED to indicate boosting activity. Each kit contains the 44 Amp PowerMAX Voltage Booster, a single plug-and-play wiring harness, a pedal harness, and a comprehensive installation kit. This kit includes a Hobbs switch preset at 5psi (adjustable 3-7psi), various fittings and vacuum hoses, fuses, and all necessary hardware for a secure installation. An optional remote-mounted voltage control knob (PM-2999) is also available for on-the-fly adjustments.
