Go Port systems use a throttle body with the ECU mounted directly on it for a simpler install. Ultra Port systems use an external ECU with upgraded fuel delivery, sensors, and wiring for more tuning flexibility and higher power levels. Both put a fuel injector in every intake runner.

Small block Chevy, big block Chevy (rectangle and oval port heads), Ford 351 Windsor, and LS engines. LS systems are available for both LS1/cathedral port and LS3/rectangular port cylinder heads.

Not with the full kits. Most Go Port and Ultra Port systems ship with the intake manifold, fuel rails, injectors, and everything else needed for a complete install. Standalone ECU kits are also available if you already have your own intake, fuel rails, and injectors.

Both are complete LS port injection systems with intake manifold, fuel rails, injectors, and transmission control. The Ultra Port LS comes with a modern throttle body in black or brilliant finishes. The Retro LS Port pairs the same port injection setup with a classic gold series throttle body for a vintage look.

Yes. Port injection systems require an EFI-rated fuel pump that delivers adequate fuel pressure. FiTech offers Force Fuel and in-tank fuel pump options designed to work with their port injection systems. Contact tech support if you need help selecting the right fuel delivery setup.
