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, fuel lines or intake manifold**

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.

•Ignition timing control does not learn, and requires synchronizing distributor to engine with a timing light.

Throttle body has 1 year limited parts only replacement. Limited Lifetime Warranty on ECU

FiTech 40004 Fuel Command Center 2

The Command Center 2 is the ultimate answer to fuel system simplicity! Designed to be used in vehicles with stock fuel tanks converting from carburetor to EFI. The Command Center 2 eliminates that problem. Complete new design from years of testing has resulted in the most effective system anywhere. The pump in the Command Center 2 never gets uncovered because it receives a steady supply of fuel from your existing fuel system. So your system maintains a constant flow of fuel. The built-in regulator eliminates the need for an external regulator. Since the Command Center 2 is constantly circulating fuel to and from your tank, your fuel pump stays cooler and will have a longer life. The fuel pump noise is also muffled by being submerged in fuel 100% of the time. The Command Center 2 is the best way to provide the necessary increase in volume when adding a power adder such as boost or nitrous to your engine. So, whether you are racing, off-roading, or just cruising, this “compact” external fuel assembly is your all in one solution.

Command Center 2 Features:

• Capable of delivering enough fuel for up to 800hp.
• A low fuel level in the fuel tank will not result in pump starvation.
• Single High Volume Flex Fuel 340 LPH pump is compatible with any EFI system.
• Maintains a 1.5 Liter (0.4 Gallons) reservoir of fuel in the module at all times.
• A submerged pump runs cooler than an external pump.
• Eliminates rigging costly EFI quality inlet and return lines for your fuel system.
• No needle seats or floats to get hung up or stick!
• Every FiTech Go EFI System is available with the Command Center 2 as an option.
• Precision machined extruded aluminum tank.
• Compatible with any other competitive aftermarket or factory EFI installation.
• Hard anodized and laser etched for durability and visual appeal.
• Compatible with E-85 gasoline and alcohol or methanol based fuels.
• Compact size makes it easily mountable in a variety of locations.

Command Center 2 Includes:

• Main assembly w/340 LPH fuel pump, regulator, pressure gauge.
• 5ft high-pressure hose & -6 AN fittings connect main assembly to throttle body.
• Hyperfuel high-flow 30-micron EFI fuel filter.
