Retrotek Boss EFI

The BossEFI simply replaces the carburetor, providing a clean muscular appearance. It is identical in all critical dimensions to a 4150 and features four high-pressure port-style injectors placed strategically above the throttle plates, providing optimum fuel atomization and power output. In direct back-to-back comparisons to port EFI BossEFI made equal or more power.

The Stage II Engine Management System has an “adaptive learning” feature that self-tunes as you drive. It takes its information from a wideband O2 sensor and control module, with no welding necessary for the sensor installation thanks to an innovative clamp that attaches to the exhaust. Another hurdle for EFI that no longer exists is the need for a fuel tank return line. The external RetroTek electric fuel pump is controlled by the ECU and provides exactly the right fuel quantity and pressure.
