A/F is a waste of time unless you buy one that also comes with the sensor that you mount in the exhaust, which these kits cost easily over 100 dollars. A vaccum gauge works better for tunning then the cheapo A/f gauges

running that lean may make your combustion temperatures too hot.

The 14:1 value is really the ideal air fuel ratio, and thats what the computer is trying to give you.
