Holley's Sniper EFI Super Sniper Stealth 650 is the best way to convert your carbureted engine to fuel injection with just 4 simple connections required. With a Stealth system, you get that carburetor styling but the functionality of a Sniper! This 4-barrel system features a single pattern bolt on design built to fit 4150 flange manifolds. The Super Sniper Stealth ECU is capable of fuel map self-learning and ignition timing control, improving idle stability, drivability, and wide-open throttle horsepower. Additionally, this Sniper kit also includes transmission kick down provisions for GM TH350/400, 200R4/700R4, and Ford C4/C6 applications! Super Sniper can support up to 650HP naturally aspirated or 600HP boosted with 4 100 LB/HR Injectors.
We want everything to be as simple as it can be for you! Sniper kits are built and designed to be installed at home in your garage or driveway with limited tools and the support of Holley's comprehensive installation manual and videos. An afternoon in the garage and you will be enjoying improved engine performance, better MPG's and easier starting. After the simple installation it's time to let your Sniper begin the self-tuning process. Our user-friendly calibration wizard allows you to just answer a few questions about your engine and the system will begin self-tuning with no laptop required.
