    From the company that brought you the "Bolt on and Go" Street Avenger carb comes the latest technology in "Bolt on and Go" fuel injection… Avenger™ EFI! The Avenger EFI is intended for users who want a "Bolt on and Go" EFI system without the need for a laptop computer! Avenger EFI systems are perfect for performance street engines, most crate engines and mild street / strip applications. Simply bolt on an Avenger™ system, answer a few easy questions and let it do the tuning for you! The secret is in the innovative Avenger™ EFI handheld tuner and the breakthrough technology of our Self-tuning fueling strategies. The compact, easy to use hand-held tuner guides you thru the simple setup wizard where you answer a few key questions about your setup. Once that basic information is loaded, you fire the car, run it thru various RPM stages and drive it to tuning perfection! The self learning strategy will automatically tune your engine as you drive to deliver the optimum air-fuel ratios for performance and mileage.

    Avenger EFI Features:
  • Self-tuning fueling strategy tunes while you drive - Designed for the user that wants ease of use without having to be a "tuning expert"
  • Requires no laptop computer to set up or tune - Included full color LED hand-held tuner offers simple setup and easy tuning of basic parameters such as engine idle speed. Still allows for users to change other parameters to further fine tune base calibrations
  • Come complete with all hardware to retrofit EFI on a non-EFI vehicle including fuel pump
  • Dedicated fuel and oil pressure inputs
  • Allows for computer controlled ignition timing if desired
  • System can be upgraded in the future to a Holley "HP EFI System" if desired
