FiTech 71003 Ultimate LS EFI 750HP Fuel Injection Systems

The LS EFI 750HP fuel injection systems by Fitech are hands down the best on the market! Many of the parts for these systems have been fabricated, including the low-profile 102mm billet throttle body, high-volume billet fuel rails, and an intake manifold with 1,500 to 6,500 rpm powerband and 3mm construction.

System includes 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.

Optional transmission control feature is suitable for 4L60, 4L65, 4L70, or 4L80 GM transmissions. The FiTech LS EFI 500HP fuel injection systems with trans controller provides great power and performance without breaking the bank.
