5.7 and 6.1L Hemi F.A.S.T XFI Standalone Tuning Kit

Complete kits include everything required to install high performance FAST™ XFI™ Fuel Injection for precise engine management and compatibility with aftermarket components

Fuel injected Hemi crate/transplant engines are an increasingly popular solution to the horsepower needs of today’s hot rod, street rod and off-road vehicle owners. These engines are very attractive because of their high factory horsepower and torque ratings combined with easier starting, better fuel economy and improved road manners. Unfortunately, these engines were designed for use with factory computers, throttle-by-wire throttle bodies and complex wiring harnesses – all components that are nearly impossible to purchase new and will leave you searching for quality used parts. The FAST™ EFI Crate/Transplant Engine Management Kit changes all of that, making it easy to convert to the FAST™ XFI™ Fuel Injection System, and includes all of those hard-to-find components and easy-to-follow instructions.

FAST™ EFI Crate/Transplant Engine Management Kits are individually tailored to perfectly match your specific brand and model of crate engine. These new kits include carefully matched components of the highest quality, starting with the industry’s most powerful, yet user friendly, fuel injection system – the FAST™ XFI™. The XFI™ Fuel Injection System comes pre-programmed with basic tune-up files for all applicable crate engines – allowing you to get up and running quickly. This system also provides the flexibility to tailor your engine’s tune-up as your knowledge and comfort level with EFI tuning grows and allows you to tune for even more horsepower with cam changes, etc.
