Hi Guys

I have been running way to rich (black sooty plugs) with my current tune (Vtech Stage 2) so going back to Stage 1 for the moment but I think its time to get a AFR Guage installed. I looked the past threads and saw that a adapter bung is required and they used to be sold on this site, but no longer available. I have a 2011 FX SHO and just want to take out the bung in the exhaust and fit the adapter\sensor with minimal mucking around. I will be making more mods as I go so wanted to leave the sensor guage installed and I see some people leave them installed and others remove them when not testing - Advise on this or which gauge would be best would be much appreciated.
