ACES EFI Killshot™ Self-Tuning EFI system is the most advanced throttle body injection (TBI) system on the market.

The Killshot™ utilizes four 100 lb./hr. fuel injectors, giving the system the capability of supporting up to 650 horsepower.

The system includes the throttle body (with integrated fuel injectors, TPS sensor, MAP sensor, IAT sensor, and stepper motors), wiring harness, wideband O2 sensor, ECU, handheld programmer for easy tuning and monitoring of engine data.

ACES’ Killshot™ TBI system fits any 4150-flange 4-barrel intake manifold and is designed for easy installation and tuning. Installation is straightforward and easy, and the system includes everything you need to get on the road or track quickly. The calibration wizard and self-tuning features mean advanced tuning knowledge or experience is not required.

Aces EFI designed its throttle body systems with the ECU separate from the throttle body. This alleviates any issues with possible damage to the ECU from unwanted engine heat or vibration. This is a common problem with other companies’ all-in-one systems.
