Holley Releases Sniper EFI 4150 2x4

Holley is pleased to announce the release of Sniper EFI 4150 2x4 Systems, a fast, easy way to upgrade dual-carbureted engines to all the tuneablity and modern benefits of EFI. They're available in two configurations – the standard version, which is ideal for naturally aspirated applications, and Super Sniper, which is compatible with both NA and supercharged engines with draw-through carburetors – and both come in three different finishes: polished, black and gold. No computer experience is required, and you don't even need a laptop to use it (though easy laptop tuning is also available via a provided USB/CAN communication cable). A single throttle-body-mounted ECU provides easy connections between the throttle bodies, so there are no extra boxes to mount.

 

Sniper EFI 4150 2x4 Systems include a full-color handheld touchscreen tuner – just answer a few basic multiple-choice questions, and the setup wizard takes over and the tunes itself as you drive. Perfect for Tunnel Rams with dual-quad carbs, they feature integrated timing control, built-in single-stage progressive nitrous control, an internal 2.5 BAR MAP sensor, and eight 100 pound-per-hour injectors to support 1,250 HP on both naturally aspirated and forced-induction setups. For engines that produce boost in excess of 21.5 PSI, the Super Sniper has three additional 0-5V sensor inputs that can be used for an external MAP Sensor, fuel pressure, nitrous pressure, or oil pressure. Every Sniper EFI can be repeated updated with free downloadable Sniper EFI software that gives you unlimited control of your engine, and Super Sniper systems come with a USB/CAN tuning cable for live engine tuning.
