Description

FiTech Ultimate LS EFI 500 hp fuel injection systems with Go Fuel in-tank module combines incredible engineering and construction for top-of-the-line performance. FiTech fabricated many billet aluminum parts for their Ultimate LS EFI 500 hp systems, including a 92mm throttle body, high-volume fuel rails, and a 1,500 to 6,500 rpm powerband intake manifold. They combine sequential spark and fuel control with 36 lbs./hr. injectors, a plug-and-play wiring harness, and a color touch screen self-learning ECU. This allows for programing two fan control outputs, most tach and speedometer output drivers, and target AFR and timing on the fly.

The Go Fuel in-tank module universal billet assembly can be used on tanks with a depth of 6 to 15 inches. The billet aluminum was designed with the supply and return ports in a parallel position to help route the fuel lines easily and evenly. The vent port is on the other side to ease routing the line near the fill tube. The two fuel ports are threaded to accept -6 AN O-ring boss fittings for a secure, leak-free connection.

Whether you're starting with a 5.3 junkyard dog or a crate motor, FiTech Ultimate LS EFI 500 hp systems with Go Fuel in-tank module will look and run exceptionally.

Additional Ultimate LS features:

* Optional GM transmission control feature is suitable for 4L60, 4L65, 4L70, or 4L80
* Black anodized aluminum parts for style and corrosion resistance
* High-flow, cable-operated throttle body
