Holley EFI
44-553-101 Holley Gauge Chrome

2-1/16” diameter gauges designed specifically for use with the Avenger, HP and Dominator EFI systems. They feature a blue numeric LED display as well as a 40 segment multi-color LED bar around the outside of the gauge. Require power and ground but are wired to a single wire output from the ECU for simple wiring. Can be connected to the vehicle headlight switch to allow dimming for better night time viewing. Each gauge can easily be individually programmed for a specific function and operation eliminating the need for other gauges and expensive dedicated sending units (battery voltage, coolant temp, oil pressure, fuel pressure, nitrous pressure, RPM, air/fuel ratio etc.). A “decal sheet” is provided with the most common inputs used so the gauges can be correctly labeled.

Nitrous and Fuel

Monitoring fuel and nitrous pressures is vitally important for maximizing the performance of any nitrous system. It is also a key function in tuning. MPS offers a variety of brands of gauges that are specially built for this task. Some brands offer standard and some offer liquid-filled gauges.

All of the nitrous pressure gauges measures from 0 - 1500 psi (although the recommended pressure is 900-950 psi) and are essential in monitoring nitrous pressure.

The Fuel Pressure Gauges measure from 0 - 15 psi or 0-100psi and are essential in monitoring fuel pressure.
