The Terminator X Max Stealth EFI from Holley supports 600 Horsepower on forced induction or 650 Horsepower on naturally aspirated applications. The Terminator X ECU can self-learn fuel maps as well as ignition timing controls. All this translates to better drivability along with improved throttle horsepower and drivability.

With this EFI, you get a stealth installation as the entirety of its wiring goes under the rear fuel injector. The air entry is machined for compatibility with majority air cleaners, and provisions are also there for its locators.

A full-color high-resolution touchscreen allows for easier initial setup and tuning with better gauge displays. No laptop is needed for the initial calibration as the wizard does it all by asking you a few questions.

A Wideband Oxygen Sensor LSU 4.9 from Bosch is also included with this EFI. And this helps you get real-time learning of the Fuel Map. You get OEM type IAC/TPS that ensures several years of excellent service. There are three finishing options available in this- black, shiny, and gold.
