Looking to upgrade your carbureted vehicle to Sniper EFI but not keen on an external fuel pump? Look no further than the Sniper EFI Master Kits, featuring a Returnless Retrofit Fuel Module. Holley's Sniper EFI Self-Tuning Master Kit is the optimal way to transition your car to fuel injection, requiring just four simple connections. Elevate your vehicle's performance with improved engine efficiency, enhanced MPG, and easier starting. The throttle body mounted ECU, absent of extra boxes, and the dual-pattern bolt-on design tailored for 4150 flange & spreadbore manifolds make this kit ideal for engines reaching up to 650hp naturally aspirated and 575hp boosted with four 100 Lb/Hr injectors!
Tuning simplicity is at the core of this kit. A user-friendly calibration wizard enables you to answer a few questions about your engine, initiating a self-tuning process without the need for a laptop. Whether you're a computer whiz or not, utilizing the high-resolution 3.5" full-color touchscreen for tuning and gauge displays is effortless.
The Sniper EFI Master Kit includes a comprehensive fuel system, incorporating a 340LPH fuel pump in the tank, easily installed with basic hand tools. The Drop-in Master kits simplify plumbing your Sniper EFI installation; cap the regulator on the Sniper EFI throttle body with the provided -6an cap, route the vapor guard fuel line along the chassis back to the diecast fuel hat, and the job is complete.
Despite having a returnless style fuel system, the Sniper is an Ecosystem. Seamlessly pair this kit with Holley's Sniper Hyperspark Ignition, Fuel Systems, Air Cleaners, Throttle Body & Digital Dash to unlock your build's full potential.
