The FAST EZ-EFI Multiport Retro-Fit kit is a self-tuning fuel injection system designed to convert carbureted or multi-port setups for applications up to 650 horsepower. The system bolts on without manifold replacement for many 4150-style carb manifolds, uses a handheld color touchscreen setup wizard for automatic tuning as you drive, and includes an updated wiring harness and a die-cast four-injector throttle body with integrated fuel rails for improved fuel distribution.
