A/F/R gauge for tuning

I bought an AEM gauge. It works pretty good. Good enough for the type of tuning that I do. (Street and occasional pass down the track) I have it rigged up temporarily with the long cable thru the vent window. I like being able to see how a metering rod change directly affects the afr. I’m about average when it comes to tuning carbs and it’s a handy tool to have. I feel like I have become more adept at tuning after adding this tool
