The Sniper EFI Sniper 2 EFI Fuel Injection System is engineered to transform classic vehicles with carbureted engines into modern performers, delivering the reliability, efficiency, and power of contemporary fuel injection technology. Designed as a direct replacement for common 4-barrel (4150 flange) carburetors, this system is remarkably simple to install – requiring only four basic wiring connections: battery, ignition, and RPM signal. The intuitive setup wizard guides users through initial calibration, eliminating the need for a laptop or advanced tuning knowledge. At its core, the Sniper 2 EFI employs advanced sensors and a next-generation ECU to monitor key engine parameters in real time, such as air-fuel ratio and throttle position. This allows the system to automatically adjust fuel delivery, optimizing combustion for smooth starts, consistent idle, and enhanced throttle response. The self-learning capability means the system continually refines its performance as you drive, ensuring peak efficiency and power without manual intervention. Supporting up to 650 horsepower naturally aspirated and 575 horsepower with forced induction, the Sniper 2 EFI is suitable for a wide range of builds. Additional features include improved RF interference resistance, a redesigned throttle shaft for smoother operation, and compatibility with the complete Sniper EFI ecosystem – offering seamless integration with Hyperspark ignition, fuel system upgrades, and multiple display options. For enthusiasts seeking modern drivability and fuel economy in their classic ride, the Sniper EFI Sniper 2 EFI Fuel Injection System delivers a compelling blend of innovation, simplicity, and performance.
