I found a AEM 30-4100 Wideband Gauge EUGO 6 in 1 Controller on Ebay for $182.00 shipped so I bit the bullet and bought one. I also bought a pair of bung plugs (yes I said bung plugs
) for $7.00 and a gauge pod for another $7. So I got the whole setup for less than 200 bucks. My last expense will be to have my local muffler shop weld the o2 bung into my exhaust.
