Help it's going crazy!!!!

I installed Universal 2" 52mm Air Fuel Ratio afr Volt Blue Digital LED Combo Gauge Smoke Len | eBay that to fill my hole its a digital volt and it is a nb afr gauge but gives u a digital afr read out seems to be around 14.6 to 15.4 crusing light throttle and lean rich at idle but at wot I am seeing 12.0 to 11.5 depending on fuel and air temp so seems to work ok doesn't flop as bad as that lol

i would be screwed with this guage!!! My car can't deside if it wants 14.3 or 15.8 volts haha so it goes back and forth!!
