Go EFI 2×4 625 HP Dual Quad Normally Aspirated
Dual Quad! EFI ! Nothing says Muscle like 2 big 4 BBL’s on a V8 . FiTech EFI has made it simple with their Go EFI 2X4 625 HP self-tuning System. This kit is a bolt on for the most popular manifolds including the Edelbrock line of dual quad manifolds WITHOUT any adapters! They fit and look like they belong there because they were designed to fit from the start. Our normally aspirated kits are good thru 625 hp but our Go EFI 2X4 POWER ADDER kit can handle you guys with the bigger cubes and Roots Superchargers. One Throttle Body handles all of the brains while the second holds 4 additional injectors, and the IAC motor for idle stability. These can also be used in cross ram and tunnel ram configurations. No boost with these please! For Boosted and High HP normally aspirated applications please see our Go EFI 2X4 POWER ADDER (Part #30064). **This kit does not include linkage or fuel lines**
Bolt on 2 of these tough looking throttle bodies and drive your car as the system dials itself into the perfect calibration for all of your driving and weather conditions. If you decide you want to tune for more power or economy, the FiTech Touch Screen controller allows quick and easy on the fly adjustments at your fingertips!
Note that this EFI system can also be used with an engine compartment mounted Fuel Command Center, which provides a returnless system. See Command Center details in the description below.
A List of features of the Go EFI 2×4 625 HP Dual Quad System:
- 8 Precision Flow matched injectors capable of flowing 625 HP of fuel.
- 2 matte black High Flow throttle bodies with mounting for Edelbrock or Holley style manifolds. Includes stainless steel polished linkages.
- Wire harness for dual quad installation.
- 4 Gig data logging.

- Basic install can be done with just 4 wires and 2 sensors to install.
- Uses a Bosch 4.2 wide band O2 sensor while all other sensors are easily replacement GM style parts.
- The ECU is mounted on the throttle body so there is NO external boxes or harnesses to clutter up your engine compartment or under dash. This saves you a huge amount of time and keeps things simple and neat.
- Throttle bodies have a base that will fit most dual quad manifolds.
- Throttle Linkage suits most transmissions.
- Choice of three fuel inlet connections.
- Die cast aluminum throttle body housing.
- All Go-EFIs feature Voltage Control fuel pump control. This feature 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!

- Will work with CDI box but not required to control timing.
- Built in Fuel pressure regulator. No extra regulator to mount on your firewall.
- Also available with optional FiTech Fuel Command Center. This allows you to use your existing fuel pump to deliver fuel to the sump tank (mounted in the engine compartment) where a 340 L/PH high pressure fuel pump is submerged in the sump.
- Use of ignition timing control is optional and not required.
- Ignition timing control does not learn, and requires synchronizing distributor to engine with a timing light.
