Description

The FiTech 70034 Ultimate LS 1000 HP EFI System is a comprehensive, self-tuning induction solution engineered for LS engines. Designed for a wide range of applications, from salvaged 5.3L engines to high-performance 427 strokers, this system simplifies the process of upgrading from factory hardware or topping off a new long block. It features a multi-port injection style, speed density metering, and is compatible with power adders like boost and nitrous oxide. The kit includes a self-learning ECU, a complete aluminum intake manifold with a black anodized finish, and a 102mm throttle body. Key components like injectors (80 lbs/hr), a wiring harness, oxygen sensor, MAP sensor, IAT sensor, and TPS sensor are also included, making installation straightforward. This system supports various fuel types including alcohol, gasoline, methanol, and flex fuel.
