When it comes to fuel injection versus carburetors, new school is just too cool. FiTech Go EFI 4 600 hp self-tuning fuel injection systems have the ECU mounted on the throttle body for greater self-containment, clean installation, and easy setup. These trick systems fit any 4-barrel intake manifold, and are designed for use on engines from 250 to 600 hp. They feature a built-in fuel pressure regulator, an ECU that finds the best tune and self-adjusts to it—and the ability to change air/fuel ratios and ignition timing on the fly.

Each system has a hand-held controller with a touch screen for initial setup, throttle linkage that suits most transmissions, and is manufactured with OE engineering. FiTech Go EFI 4 600 hp self-tuning fuel injection systems leave the guesswork behind. Order the model with options best-suited for your application.

Additional features:
• Choice of three fuel inlet connections
• Will work with CDI box, but not required to control timing
• Adjustable fan control switch
• Can be used with an engine-mounted returnless fuel command center
