FiTech 30003 Go Street 400 HP Throttle Body EFI Kit

The days of fumbling through jets and metering rods are over. Switching from a carburetor to EFI has never been easier. This 4-injector throttle body replaces your current 4-barrel carburetor for high performance EFI. The FiTech Go Street EFI is priced just above many off-the-shelf carbs, but the advantages of going fuel injected over carburation far outweigh the small difference in price. The FiTech ECU lets you regulate your air/fuel mixture and also controls several vital engine functions as well. It features an electric fan controller, fuel pump driver (eliminating the need for a fuel return line), and an integrated fuel pressure regulator ensures the unit is always at the correct fuel pressure without additional expense. The wet-flow annular discharge design improves fuel atomization and distribution over traditional 1980s OEM throttle body injection designs.

The Go Street EFI 400 HP kit is the most economical kit in the FiTech product line and is designed to work with most naturally aspirated small block street applications. It contains all of the same features as the other FiTech EFI kits, except for smaller, less costly fuel injectors (150-400 horsepower) and no timing control over the ignition system. This game-changing aftermarket fuel injection kit offers all of the latest technology and tuning software via a simple hand held controller. The self-learning ECU will continually adjust the fuel maps to increase efficiency and performance, while still allowing the user to adjust inputs on their own.
