AEM Failsafe wideband/boost gauge. $200 Shipped. SOLD Gauge and all harnesses are brand new. Comes with multiple gauge faces (white and black) and bezels (black and silver). The wideband sensor was ran for three weeks on another failsafe gauge. Dual function gauge. Boost and wideband with the added benefit of continuous data logging (boost, A/F and rpm) and failsafe outputs. http://www.aemelectronics.com/wideband-air-fuel-systems-15/wideband-failsafe-gauge-84/ Will include a used Auto meter dual guage pod if I still have it when the gauge sells. It is posted on another FS thread here.
