FiTech GM TPI Retro-Fit Standalone EFI Systems

Modern EFI Technology for Your GM TPI Engine

FiTech's Retro-Fit Standalone EFI Systems bring outdated GM TPI (Tuned Port Injection) engines to the next level. They replace the need for computer chip burning or a laptop with self-learning technology. Each system uses a handheld controller, speed density, and a wideband air/fuel controller to deliver performance, tunability, consistency, and an all-around better driving experience. Compatible with stock to highly modified applications and feature transmission control for a more user-friendly experience.
