The wideband gauge is one of the most important gauges to have in a turbocharged vehicle or any high-performance vehicle for that matter. Tuners will use wideband gauges to set the strike zone for your tune, and if you are running too rich your car will not run to its full potential, and if you're running lean, then you risk blowing up the motor.

Revel gauges feature an Organic Light Emitting Diode which when compared to your typical LCD display, the OLED display provides a sharper contrast which results in a deeper black display to provide a more clear image that is more reader friendly at a quick glance. This technology also allows for undistorted viewing angles approaching 170 degrees. This technology also does not require a backlight to be clearly visible at night which also allows for a slim profile of the gauge.

This is the Revel VLS (Visual Oled System) 52MM Wideband Gauge. This gauge reads from 10.0:1 to 20.0:1 AFRs and employs a bosch 4.9 LSU sensor. Other features include a digital OLED display with a 30 LED outer ring. Also included is the required wiring, along with a gauge cup, a gauge visor, and miscellaneous hardware to make this gauge ready for installation.
