After a little more reading up, with mid 13s you should be fine as long as you run premium. To be safe you could invest in an afr gauge to monitor it. If you get up to 14 then you should be worried.
Also, one more question... When we run lean like that, does that technically improve gas mileage? I'm just curious, I know with uprev we can get a economy map, but I'm just wondering for information sake if running lean gives any improvement over stock?
