Introducing Holley Super Sniper EFI! Looking to convert your blow thru carbureted turbo engine to EFI? Look no further than Holley for the Super Sniper 4150 EFI systems featuring 8, 100LB/HR Fuel Injectors capable of supporting up to 1250 HP on forced induction or dry nitrous applications.

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.
