These are all ballpark estimates and are greatly affected by an individual engine's displacement and volumetric efficiency. NA maximums are generally limited based on airflow. Boosted and Nitrous maximums are generally limited based on fuel injector capacity. All of these estimates assume gasoline. Adjust accordingly for E-85.

Sniper EFI System Replacement and Upgrade Components has everything you need to accessorize, repair, or update your Sniper EFI System!
EFI Pro Hangout is where our in-house Holley Tier III Technician Chris Myer shares the secrets nobody else offers about the Sniper EFI System. He's not only answered the questions you have, he's answered some you don't even know you have yet. Be sure to check that out!
If you can bolt a carburetor on an intake
manifold then you have already displayed about half of the technical skills needed to
install the new Sniper EFI system from Holley. Imagine--hard starts, hesitations, vapor
lock and flooding are all replaced by EFI reliability at a cost not much above a
high-end carburetor!
You see, Holley has done away with the ECU box entirely! The new Sniper family of Throttle Body EFI systems incorporates the ECU right into the throttle body. The benefit is obvious to most folks but allow us to elaborate. With the ECU built into the throttle body injection unit, there is really no need for a harness, in the traditional sense. Nearly all of the sensors are built into the throttle body, so all you have to do is add a few basic connections (like power, and plug in the wideband O2 sensor and a timing signal) and you're in business!
But don't think that you're getting short-changed. Holley engineers were tasked with producing a system that would have virtually all of the features of the Avenger and HP kits--and they have accomplished just that. Want to add some of Holley's beautiful analog-display gauges? You can. Need advanced tuning capabilities? The included 2.5-inch touchscreen display can do that. This isn't just a good place to start your EFI adventure--the Sniper will support whateveryour hot rod goals may be in the future.
