Holley/MSD is pleased to announce the release of Sniper EFI's High-Horsepower Super Sniper 4150 in two versions – one with eight 100 pound-per-hour injectors for forced-induction engines making 1,250 horsepower (or naturally aspirated engines making up to 700 horsepower), and one with four 100 pound-per-hour injectors for blow-through/forced induction engines making up to 650 horsepower. Both have built-in single-stage progressive nitrous control, so there's no need for the unnecessary added expense of a separate nitrous controller. These Super Sniper systems also come with an additional 8-pin connector harness that grants additional programmable inputs/outputs and sensor functionality over our standard $999 Sniper EFI systems.

Ideal for converting blow-through-carburetor turbocharged engines to EFI, the high-horsepower Super Sniper 4150 is equally suitable for draw-through and blow-through forced-induction engines. These bolt-on EFI conversions feature a user-friendly boost control with handheld adjustability and a fully programmable target air/fuel ratio per boost level. Advanced boost control is available through free downloadable Sniper EFI tuning software, including boost-vs.-rpm and boost-vs.-time – the same boost control that has become so popular with Holley HP and Dominator EFI. Compatible with both wet and dry nitrous systems, they also feature programmable inputs and outputs, time-based or RPM-based timing retard, a USB/CAN tuning cable, and even a lean/rich AFR cutoff.
