FiTech Ultimate LS EFI 750 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 750 hp systems, including a 102mm 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 55 lbs./hr. injectors, a plug-and-play wiring harness, and a color touch screen self-learning ECU.

FiTech Ultimate LS EFI 750 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 750 hp systems, including a 102mm 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 55 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. 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 * Bosch wideband-controlled * Stainless oxygen sensor bung * Compatible with car and truck coils * AN fittings and fuel crossover * Works with custom cams * Designed for applications making at least 6 in. of vacuum at idle * 24X and 58X crank and cam compatible * Programmable touch screen hand-held controller with data log features * Suction cup mounting bracket
