Naturally aspirated air/fuel ratio

[0llll0]

There is allot talk about air/fuel ratio on here about turbo sleds but I can't seem to find much about the n/a air/fuel ratios or does it matter if it's n/a or turbo? Curious to know what kind of numbers I should see with just a aftermarket muffler on the sled?

Based on what I see... startup and idle at 12.5 to 13 and if you can pretty much keep it at 12.5 thru out the driving range it would be damn close.
