What would the Air to Fuel Ratio be on a hot truck.

Could be worse!
Just doing some calculations and I see that a A/F ratio of 22/1 is ideal with low or no smoke performance. Obviously this is not the case on alot of our trucks I'm looking for a real world number that would be in the ball park for let's say a 13mm pump with some 5x18 sticks. Is 15/1 to low or high it makes a pretty big difference when you plug the numbers in to find out the Air and boost requirements for a desired HP setup.

22/1 = 50 PSIA and 97Lbs of air

15/1 = 35 PSIA and 67lbs of air

Just looking for some more accurate numbers to use in the formula.
Thanks
