FiTech 79630 Ultimate LS 1000 HP EFI System Master Kit

The FiTech Ultimate LS 1000 HP EFI Systems deliver elite-level, self-tuning multi-port fuel injection for GEN III/IV LS-based small block Chevy engines, supporting up to 1,000 horsepower to the flywheel with a 1,500-6,500 RPM powerband. These complete induction kits feature a low-profile 102mm high-flow throttle body, fabricated 3mm thick TIG-welded aluminum sheet metal intake manifold (short or long runner options for cathedral port heads like LS1/LS2/LS6), 3-bar MAP sensor for power adder compatibility (up to 30 psi boost), sequential spark/fuel control, high-flow injectors (typically 80 lb/hr), plug-and-play harness, color touchscreen self-learning ECU with handheld suction-cup mount, dual fan outputs, tach/speedo drivers, on-the-fly AFR/timing adjustments, and optional transmission control for GM 4L60/65/70/80Eeliminating mismatched parts, harness splicing, or third-party reflashing for fast, reliable LS swaps or upgrades.

Optional Go-Spark LS3-style coil packs provide bolt-on replacement with optimum output, perfect fit, sealed locking connectors, and plug wire terminals for enhanced spark reliability and performance in EFI setups.
