The Holley Terminator X Max Stealth 4150 EFI system (P/N 550-1028) provides modern EFI benefits with a classic carbureted look. It supports up to 650 HP naturally aspirated or 600 HP with forced induction, utilizing four 100lb./hr. fuel injectors and a genuine Bosch LSU 4.9 Wideband Oxygen Sensor. The system features self-learning fuel maps, integrated ignition timing control, and a fuel pressure regulator set to 58.5 PSI. It offers plug-and-play transmission control for GM TH350/400, 200R4/700R4, 4L60, and 4L80 transmissions, and includes kick-down provisions for Ford C4/C6 applications. Designed to fit LS engines with 24x crank, its air entry is machined for most stock-style air cleaners, and all wiring exits below the fuel injector bowls for a clean appearance. Setup and tuning are simplified with a high-resolution, full-color touchscreen and calibration wizard, eliminating the need for a laptop.
