Holley (550-443): Terminator Stealth EFI Kit with GM Transmission Control

Have you resisted switching to EFI because you like the traditional look of a carburetor? Do you have a GM 4L60/80E transmission in your hotrod? Stop worrying! Holley’s recently released Terminator Stealth throttle body fuel injection system gives you all of the benefits of EFI with the traditional carburetor look you love.

The 550-443 Terminator Stealth EFI system possesses the same great self-tuning features of Holley’s original Terminator EFI in a stealthy new configuration. Holley has made this new system easy to install, with no computer experience required and an included hand-held tuner with multiple-choice setup wizard to get you up and running quickly. Even better, the system self-tunes while you drive, and you can upgrade to complete laptop control without buying another ECU. Available in Polished and Hard Core Gray finishes.
