Info

Introducing Holley Super Sniper EFI! Looking to convert your blow thru carbureted turbo engine to EFI? Look no further. Holley offers a 650 HP four injector version for lower horsepower applications with a power adder or someone just needing additional sensor inputs. Did we mention the Super Sniper also has full nitrous control built-in? That's right, no need for a separate nitrous controller! Every Super Sniper EFI system also comes with a USB to CAN tuning cable, as well as free downloadable Sniper EFI Software to give you unlimited control of your engine.
