Dual Quad Upgrade Kit must be used in conjunction with an original FAST™ EZ-EFI® Self Tuning Fuel Injection Kit, part #30226-KIT or #30227-KIT.

The original FAST™ EZ-EFI® featured patent pending technology with the most advanced self tuning control strategy available anywhere today. You could simply hook up the necessary wires, answer the basic setup Wizard questions on the included hand-held display and the system tuned itself as you drove. But now there is an EZ-EFI® Dual Quad Self Tuning Fuel Injection System that features all of this same technology and is capable of supporting up to 1000+ horsepower engines and has the ability to double your fuel capacity!

This new system is offered as an upgrade kit to the existing EZ-EFI® kits* and adds several additional parts, including a second unique throttle body for use with existing dual quad carburetor-type manifolds, injectors and a basic linkage kit necessary to hook the two throttle bodies together (works with most inline manifolds).

The original FAST™ EZ-EFI® Self Tuning Fuel Injection System is a complete kit that includes the ECU, wide-band oxygen sensor, wiring harness, fuel injectors, optional fuel pump kit and other assorted components, including the innovative 4150 Throttle Body from FAST™ The FAST™ 4150 Throttle Body delivers the total package approach for anyone with an existing 4150-type intake manifold. Everything comes with the kit, including appropriate fuel injectors and fuel rails. In addition, it works with the original carb-style throttle linkage and is ready to accept all OEM sensors.
