Holley Releases Sniper Stealth 4500 EFI Systems
A simple calibration wizard handles the initial setup, so there's no need for extensive tuning on a laptop. Simply answer a few basic questions about your engine, and the high-resolution full-color touchscreen wizard creates a base map and starts tuning completely on its own. The system even comes with a USB/CAN tuning cable for laptop tuning and free downloadable Sniper EFI software.
Fully compatible with both draw-through and blow-through forced-induction applications, they feature integrated ignition timing control and a programmable launch control via a two-step and timing retard, either of which can be triggered by a trans-brake. It features -8AN fuel inlets, a Gen 3 Ultra Dominator-style four-bolt air cleaner flange, and 2.125-inch throttle plates that flow 1440 CFM for larger cubic-inch engines. There's a built-in single-stage wet or dry progressive nitrous controller and three programmable 0-5v sensor inputs for oil/fuel/dome, nitrous pressure, or any other critical information you select, and the included genuine Bosch LSU 4.9 wideband oxygen sensor provides real-time fuel-map learning.
