Killshot 2 Pro EFI System

The Aces Killshot 2 Pro EFI System offers a premium upgrade from carburetors to electronic fuel injection for classic engines. Designed with a 32-bit automotive-grade processor, it supports up to 650 HP for naturally aspirated applications or 550 HP for boosted engines. The throttle body features a 4150-style flange and a 1,000 CFM rating, ensuring optimal airflow and power delivery. This system is self-learning, ideal for stock to mild engine builds, but also capable of advanced manual tuning. It includes a cast aluminum throttle body, ECU, choice of handheld or Bluetooth module, a full harness, and essential sensors like MAP, coolant temperature, and a 4.9 WBO2 sensor. The Killshot 2 Pro is E85 compatible with proper tuning and can handle up to 26 lbs of boost, with the ability to retard timing (though a separate controller is needed for boost control functions like wastegate). For optimal performance and timing control, the system requires a magnetic pickup distributor locked out or a Hall Effect distributor, and a fuel system capable of 43-58 PSI. It also features a low-profile design for improved air cleaner fitment, built-in fuel pressure sensor, progressive linkage, and expanded VE and spark tables. The system includes a 5-1/8" air cleaner diameter compatibility and is built with a 3-year warranty.
