Product Description

The DeatschWerks 4-01-VB40aX1 Voltage Booster is a high-performance module designed to elevate the power supply to your fuel pump. By boosting voltage, it ensures stable fuel delivery under heavy load or high-demand tuning conditions. This unit supports a maximum of 40 amps, making it suitable for single-pump setups with high flow requirements.

Featuring a user-friendly OLED screen and a roller-wheel interface, you can easily adjust voltage, ramp rates, and trigger modes. Whether you're running a brushless pump or a standard one, the booster's configurable modes help you get the most out of your fuel system. Security is also built-in, with passcode protection to lock in your settings and prevent tampering.

The plug-and-play harness is specifically made for Ford Mustangs, making installation straightforward without major wiring modifications. It's ideal for performance builds where fuel pressure stability is key - such as forced induction, E85, or heavily tuned naturally aspirated setups. Proper installation ensures improved fuel consistency, responsiveness, and reliability in high-demand scenarios.
