Hello, I am sorry if my question is stupid!

I went to dyno my Z today and the guy told me that my car is a bit lean or AFR lean? If my spell is right? What is that mean? Can any one explain to me plz? He said that it might does a little damage to my engine!!! He told me that the AFR should around 14 and my one is a bit low or something? and he ask me to buy a ECU flash to tune the engine!! I am really confusing? Don't know what is it mean?

I have FI CBE system, Stillen G3, Berk HFC on my car.
