You're sure to get some attention when you pop the hood and show an Avenger Stealth Ram™ Multi-Point EFI system! Available for traditional or Vortec headed SB Chevys, the Avenger's self-tuning capabilities make it as easy as 1, 2, 3 to get your car up and running with EFI. The tunnel ram design of the Stealth Ram™ builds power in the upper RPM range while maintaining excellent mid-range torque as well. Avenger Stealth Ram™ systems include: intake manifold, billet throttle body, ECU, wiring harness, fuel rails, injectors, fuel pump and related small parts. Set up is done on the included hand-held tuner so no laptop is required!

Features:

  • Self-tuning fueling strategy tunes while you drive - Designed for the user that wants the ease of use without having to be a “tuning expert”
  • Requires no laptop computer to set up or tune - Includes full color OLED hand-held tuner that 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
  • 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
