Features
Vehicle Compatibility and Return Conditions.
This item was designed and engineered in the USA for US domestic vehicles. OBD tools, ECUs, dongles, programmers, and tuners may have limited compatibility with vehicles outside the USA due to regional differences in emission standards and system configurations. Some features and functionality may vary depending on the vehicle and location.
Some electronic tuning devices and programmers require activation, registration, or pairing with a specific vehicle’s VIN (Vehicle Identification Number). Once activated or paired, these devices may become permanently associated with that vehicle, restricting or preventing their use on another vehicle, resticting our ability to offer returns or exchanges.
Please review the product details and images to ensure it meets your needs. For clarification or assistance, feel free to contact a StreetFX agent. Note: Returns are not accepted for special order or tuning products unless the unit is deemed faulty.
Images are supplied by the manufacturer and may be generic. While all efforts are made to provide accurate pictures, there may be differences in the actual product, such as colour, quantity, version, or included components. Please carefully review the description and specifications for details on inclusions or any variations. Some items may be sold individually or in sets, and images may occasionally depict additional products or quantities not included in your purchase. For assistance or clarification, please contact customer support.

Fuel Injection System, Go EFI 4 Power Adder 600 HP Self-Tuning, Throttle Body, Black Powdercoated, Injectors, ECM, Kit
If you're running a supercharger, blower, or nitrous, and want to ditch the carburetor, you'll need a FiTech Go EFI 4 Power Adder 600 hp self-tuning fuel injection system. These units mount the self-adjusting ECU on the throttle body, fit any 4-barrel intake manifold, and are designed to support 250 to 600 hp engines. Each system has a hand-held controller with a touch screen for initial setup, a throttle linkage that suits most transmissions, and is manufactured with OE engineering. Models are available with or without a fuel pump. Increased performance is at hand with FiTech Go EFI 4 Power Adder 600 hp self-tuning fuel injection systems.
Additional Go EFI 4 Power Adder features:
• Throttle body is boost-ready
• Can change air/fuel ratios and ignition timing on-the-fly
• Choice of three fuel inlet connections
• Will work with CDI box, but not required to control timing
• Two adjustable fan control switches
• Can be used with an engine-mounted returnless fuel command center
• Uses easy-to-replace, GM-type sensors and Bosch 4.2 wideband oxygen sensors
• Wet flow swirl spray annual discharge obtains complete atomization
• Built-in pressure regulator
• Voltage-controlling fuel pump control reduces power under low loads to lower temperatures
• Nitrous and boost timing retard strategies and target A/F options
• Air conditioning idle speed input kick-up
• Many safety features and accessories for nitrous tuning control
• Can handle 25 lbs. of boost from a blow-through turbo, blower, or single roots supercharger—and can also take a single stage of wet nitrous
• Complete tuning from Pro Laptop software
• Systems with mounted ECUs offer spark control without the need for an external spark box or special distributor
• Designed for applications making at least 6 in. of vacuum at idle
