Sniper 2 EFI 4BBL Self-Tuning Base Kit Upgrade to a modern, self-tuning EFI conversion specifically designed for common 4-barrel (4150 flange) carburetors. The Polished 800 cfm 4 Injector Throttle Body pairs with four precision injectors to deliver up to 650 hp naturally aspirated or 575 hp on boost, giving you the power, efficiency, and drivability you want from a street-friendly EFI system. Key features that set Sniper 2 apart
- Self-tuning calibration wizard: answer a few simple engine questions and the base map is created to begin self-tuning right away—no laptop required, no guesswork.
- Minimal wiring footprint: only four connections needed—Battery+, Battery−, Switched Ignition, and RPM (NEW). A discreet “Hidden Harness” exits from the rear of the throttle body for a clean install.
- Optional Power Distribution Module (PDM): isolates the core EFI and ignition wiring in one compact location. With a battery and a switched 12-volt source, power is simple and tidy.
- Robust engineering for real-world wiring: next-generation ECU design improves RF noise and interference resistance, helping you avoid glitches from old car wiring, noisy alternators, or faulty plug wires.
- Smooth, responsive throttle: redesigned throttle shaft and plate geometry deliver a refined and predictable throttle feel.
- Part of the Sniper EFI Complete Ecosystem: use alongside plug-and-play Hyperspark ignition systems, fuel systems, displays, and more for a seamless upgrade path. The main harness includes plug-and-play HyperSpark distributor support for integrated timing control (adapters for other ignition types sold separately).
- Flexible display and tuning options: various tuning and gauge interfaces are available, including a 3.5-inch full-color LCD handheld, with additional display options to suit your setup. Designed for garage installation, with comprehensive installation manuals and videos to guide you through the process. Sniper 2 EFI makes classic ignition and fuel systems feel modern—delivering easy cold starts, smooth drivability, and improved fuel economy without compromising performance. If you’re seeking a high-performance EFI that combines power, efficiency, and simplicity, Sniper 2 EFI is built to deliver.
