Overview

The Holley Terminator X is an EFI system designed for 1987-1993 Fox Body Mustangs equipped with a factory 302ci Small Block Ford engine and stock TFI distributor. This kit provides complete engine control with self-learning fuel strategies, replacing the factory ECU for improved performance and tunability.
