Modernize Your Carbureted Engine With a FiTech Self-Tuning Throttle Body Fuel Injection System

If you have a muscle car, hot rod, or street machine and thought about making the switch to EFI, FiTech has you covered. Their systems provide the best of both worlds. You get to keep the classic under-hood look you love while adding modern-day advantages like improved throttle response, reliable cold starts, and new car drivability.

FiTech’s Throttle Body EFI Systems are bolt-on, which makes it easy to swap out your current four-barrel carburetor for one. They’re also self-tuning, automatically adjusting the air/fuel ratios and timing while driving.

The Go EFI 4 Power Adder 600 HP Self-Tuning Fuel Injection System is a perfect example of what FiTech offers. If your beast runs a supercharger, blower, or nitrous, and you’re ready to make the EFI swap, this system may be for you.

The kit mounts the self-adjusting ECU to the throttle body. It fits any four-barrel intake manifold and supports 250 to 600 horsepower engines. The handheld touch-screen controller is easy to use for initial setup. Models are available with or without an electric fuel pump.

Other features include:
• Throttle body is boost-ready
• Throttle linkage suits most transmissions
• Self-learning ECU continuously adapts to engine changes and driving conditions
• Nitrous and boost timing retard strategies and target air/fuel options
• Safety features for nitrous tuning control
• Can handle 25 lbs. of boost from a blow-through turbo, blower, or single roots supercharger
• FiTech’s rolling updates deliver continuous product improvements
• Three-year limited warranty

If this system is not for you, that’s OK because FiTech has many different throttle body EFI systems to choose from. They have kits in a variety of two-barrel, four-barrel, and classic six-pack versions to fit a wide range of engines, from mild street builds through high-horsepower applications. This includes naturally aspirated, nitrous, and boosted combinations. Plus, there are multiple finish options, including natural aluminum and black, to complement your engine bay.
