All Sniper 2 650 systems share the same next-generation throttle body, ECU, and performance capability. Kit selection does not change horsepower or drivability—it only changes how complete the fuel system and electrical management are.

Sniper 2 is a self-tuning EFI conversion for 4150-style carburetor applications, designed for easy at-home installation and modern OEM-style driving manners. Every system supports up to 650 HP naturally aspirated or 575 HP boosted, using four 100 lb/hr injectors and a genuine Bosch LSU 4.9 wideband oxygen sensor for continuous self-learning.

New features of the Sniper 2 deliver the next level of EFI refinement with a hidden rear-exit harness for a clean engine bay, redesigned throttle body and injector connectors for improved reliability, and a next-generation ECU with enhanced RF noise resistance built to handle classic vehicle wiring. Mil-spec M8 CAN bus connectivity, integrated transmission kickdown provisions, and smoother throttle shaft and plate geometry further elevate performance and drivability. With plug-and-play HyperSpark distributor support, multiple tuning and display options (handheld, digital dash, or Bluetooth), and full compatibility with the Sniper EFI Ecosystem, Sniper 2 sets the standard for modern bolt-on EFI systems.


Simple Wiring
No complex EFI conversions here! Get your vehicle up and running in as little as four wires - battery, switched ignition, and RPM. Sniper is an ecosystem and is designed to support the needs of your build


Simple Setup
The only thing easier than the installation is the setup. Our intuitive wizard seamlessly walks you through the process. There's even multiple screen options - from the tried and true 3.5-inch handheld, 5-inch dash, through to our app enabled Bluetooth module. Tuning should always be this easy. Sniper 2 supports up to 650hp naturally aspirated and 575hp boosted with its onboard 2.5 BAR MAP sensor


Optional Power Distribution Module
One of the most exciting products designed to support the Sniper 2 ecosystem is the Power Distribution module (PDM). This cost-effective and optional accessory isolates the core of your EFI and ignition wiring into one, easy to use location. Simply slide the stripped wire ends under the positive lock connector and tighten down the set screw. Battery and a switched 12 volt source is all that's required from your vehicle to power the PDM


Sniper 2 Ecosystem Support
