FiTech Ultimate LS EFI 500 HP Fuel Injection Systems

FiTech has some of the best-engineered and priced throttle body systems on the market. Their LS EFI 500HP fuel injection systems bring incredible ingenuity to the market. FiTech fabricated many aluminum parts for these systems, including the low-profile 92mm billet throttle body, high-volume billet fuel rails, and an intake manifold with 1,500 to 6,500 rpm powerband and 3mm construction.

Sequential spark and fuel control mates 36 lbs./hr. injectors, a plug-and-play wiring harness, and a color touchscreen 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. A suction cup mounting bracket puts the controllers at your fingertips and allows for impressive visual aids.

The optional transmission control feature is suitable for 4L60, 4L65, 4L70, or 4L80 GM transmissions. FiTech LS EFI 500HP fuel injection systems with transmission controller provide impressive power and performance, while allowing you to save a little green for your next tires.
