The Terminator X Stealth 4150 system features (4) 100 lb./hr. fuel injectors capable of supporting up to 650 HP naturally aspirated or 600 HP on forced induction applications. Taking the Stealth name, all of the wiring exits below the rear fuel injector cover for a clean installation. The timed spark port for vacuum advanced distributors is located under the front fuel bowl, giving greater access to the distributor. Air entry is machined to fit most stock air cleaners with air cleaner locator provisions. The ECU features fuel maps that self-learn and integrated ignition timing control, yielding improved idle stability, drivability, and horsepower at wide-open throttle (WOT). The Stealth 4150 also includes transmission kick down provisions for GM TH350/400, 200R4/700R4, and Ford C4/C6 applications for making installation more convenient. These kits provide plug and play transmission control for GM 4L60 and 4L80 transmissions.
