The Go EFI 4 Self Tuning Fuel Injection is rated at 600 HP but is suitable for engines from 250 HP thru 600 HP. This system is perfect for your everyday Driver right up to your weekend Street Machine or Bracket Racer. It features the FASTEST most accurate Self Learning available, Timing control, Wet flow Annular discharge and tons of additional features.

It fits any 4-bbl intake manifold and is the most self-contained and full-featured unit of this type. The ECU (computer) is mounted on the throttle body, which greatly simplifies installation. No hole in your firewall and no unsightly harness draped across your engine. This is also the only computer mounted throttle body that offers spark control without the need for an external spark box or special distributor. It also has a built-in fuel pressure regulator. A hand-held controller features a touch screen for quick and easy initial set-up.

Note that this EFI system can also be used with an engine compartment mounted Fuel Command Center, which provides a returnless system.
