. What is an unfamiliar with this gauge, the air-fuel ratios provided under boost tells you whether you are running lean. or rich. More importantly, it is a tool utilized by tuners they use to provide a solid tune for your car. If you are running lean under peak boost for example, and you see your gauge is running a 13:1 ratio under peak boost then you are at risk of blowing your motor. If you are running below a 10:1 Air Fuel Ratio then you are running too rich, and you risk washing a cylinder out.
If anything, it is insurance for your engine. If you are not hitting your target A/F ratios, then it can be an indication of something not up to speed in the motor such as a vacuum leak, bad gasoline, or fouled spark plugs. But bad A/F ratios will alarm you to stay off the boost until you get the issue addressed.
