The original FAST® EZ-EFI® featured 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 1200+ horsepower engines and has the ability to double your fueling 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).
