FAST™ engineers set out to develop the ultimate fueling strategy for the EZ - EFI ™. The EZ - EFI™ features patent pending technology with the most advanced self tuning control strategy available anywhere today. Simply hook up the four necessary wires and any optional wires, answer the basic setup Wizard questions on the included hand-held display and the system tunes itself as you drive. Countless research and development hours were spent on a number of prototype test vehicles to develop a high-quality system truly worthy of the FAST™ brand.

Capable of supporting up to 550 horsepower engines, the FAST™ EZ - EFI™ Self Tuning Fuel Injection System can be purchased as a complete system, including 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 & is ready to accept all OEM sensors.
