Engineered. Integrated. Proven.

Hold your horses

Experience the same quality and reliability you have come to know with the Killshot line of products. The Killshot Fusion supports up to 650 HP with (4) 100 lb/hr injectors.

Boost it, baby.

As you have come to expect, the Killshot Fusion also has a built in 3-bar TMAP sensor that allows you run draw through or blow through setups and support up to 27 lbs of boost.

Better Ingredients. Better Performance.

Engineered from the ground up, the Fusion’s ECU is fully integrated into the throttle body for maximum simplicity and strength. Every detail was tested and proven to withstand heat, vibration, and interference. The result is a rock-solid all-in-one system you can trust where others fail.

If the shoe (throttle body) fits

The Killshot Fusion still uses the common 4150 style flange found on many classic engine manifolds making it a very versatile when it comes to compatibility. As long as the TBI unit fits, is within the appropriate HP range, and your engine uses a classic distributor, it's a match made in heaven...or the garage.

Everything in one Place

The built-in ECU and harness gives you a simple install to give a cleaner finish. For those of you not wanting to put the ECU in the Firewall or Fender!

Everything’s good. The only thing I can say is it says on their site anything over $200 has free shipping but yet they charge me shipping.

You're going to make a video on doing an install do a complete install and show all the issues that you have doing the install and also if you're selling a product like this don't do half-**** stuff on the wiring and things it just makes things look so cheesy
