Holley EFI engineers have been hard at work expanding their popular Terminator X platform to work with even more applications! Their new Stealth 4150 models resemble a Holley XP carburetor but have four 100lb/hr injectors hidden inside the throttle body. The external ECU can be fully programmed with four inputs and four outputs as well as the ability to handle a single stage of nitrous, or integrated boost control! Following that up, Terminator X MAX systems have been announced for both Gen III Hemi Drive-By-Wire and Ford Modular 2V/4V platforms. Click here to learn more!

The Terminator X Stealth 4150 EFI system from Holley features four 100lb/hr fuel injectors capable of supporting up to 650HP naturally aspirated or 600HP on forced induction applications. The Terminator X ECU is capable of fuel map self-learning and ignition timing control, improving idle stability, drivability, and wide-open throttle horsepower! The Stealth 4150 also includes transmission kick down provisions for GM TH350/400, 200R4/700R4 and Ford C4/C6 applications! Terminator X Max Stealth 4150 kits provide transmission control for Pre-2009 GM 4L60E/4L80E Transmissions (Part numbers 550-1011, 550-1012, 550-1013). These systems are available in three finishes, gold, silver or black.
