Holley/MSD is pleased to announce the release of Sniper Stealth 4500 EFI Systems. These systems are developed specifically for upgrading drag race and high performance street vehicles to EFI, and are capable of supporting up to 1,500 horsepower naturally aspirated and up to 1,250 on forced induction applications. They feature eight 100-pound-per-hour fuel injectors and multiple input and output options to give you unlimited control of your engine. 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.
