For any serious combo, complete monitoring of air/fuel ratios and precise control over them is necessary. The FiTech Go EFI Power Adder series is capable of managing your fuel and ignition systems with great accuracy. From mild to wild, FiTech Power Adder EFI can handle intricate turbo, supercharger, nitrous, and blower applications with ease, precision and logical tuning tools. 

FiTech is the leading name in aftermarket fuel injection kits for good reason, bringing not only economy to the market, but simplicity through design. FiTech’s technology is designed and developed using OEM level engineering and components. All throttle bodies have built in computers and sensors reducing the amount of wiring to route in your vehicle. The sensors are OEM style for proven reliability and easy replacement.

FiTech Go EFI Power Adder EFI offers all of the latest technology and tuning software via a simple interface touchscreen. Full control of the ignition system is available, including selectable RPM curves and boost/nitrous retard strategies. The Power Adder units are also laptop tunable and feature data logging capabilities to help you dial in your combo.

The FiTech ECU also controls several vital engine functions including dual adjustable electric fan controls, fuel pump voltage regulation to reduce noise and heat buildup, and an integrated fuel pressure regulator ensures the unit is always at the correct fuel pressure. The wet flow annular discharge design improves fuel atomization, distribution, and intake charge cooling, which is critically important for boosted engines.

  • Basic install can be done with just 4 wires and 2 sensors to install
  • ECU is mounted on the throttle body so there is NO external boxes, harnesses or relays to clutter up your engine compartment, saving you time and keeping things simple & neat
  • Uses a Bosch 4.2 wide band O2 sensor while all other sensors are easily replaceable GM style parts
  • Air/fuel ratios can be optimized on the fly as you drive! Try that with your carb.
  • Throttle bodies have a completely universal base to fit any 4-bbl carb manifold
  • Throttle linkage suits most transmissions
  • Choice of three fuel inlet connections
  • All Go EFI’s feature Voltage Control fuel pump control which reduces the voltage to the pump under low load conditions such as idle and cruise thus reducing noise and heat. This will extend the life of your pump and keep the fuel in the tank cooler and your ears from ringing!
  • Go EFI features wet flow technology with a unique Swirl Spray Annular discharge design that assures COMPLETE ATOMIZATION! Check out our videos, you need to see it.
  • Ignition timing can be controlled and adjusted on the fly from your touch screen controller
  • Use of ignition timing control is optional and not required
  • Will work with CDI box but not required to control timing
  • Ignition timing control does not learn, and requires synchronizing distributor to engine with a timing light
  • Built in fuel pressure regulator means no extra regulator to mount on your fire wall
  • Air Conditioning idle speed input kick up

These fuel injection systems are backed by a 1 year manufacturer warranty. Tuning and technical support is available through the phone and online support by the way of tech articles and emails. FiTech Go EFI will provide lower idle RPM, cleaner start up and crisp throttle response that the best carb tuners in the world can’t match and it only comes with FiTech technology.
