The reason I ask is because I just recently dynoed my car and my a/f @ WOT is steadily @ 13.xx it doesn't really move from there now the guy who dynoed the car said I was fine. I'm not sure if I'm rich but I think so. My question is what a/f ratio should I have at WOT with mods in sig?

13.xxx is a little on the lean side at WOT. I think that ideal is in the neighborhood of 12.7-13.0

if you're running somewhere in 12.9-13.1 thats mean you're fine there buddy

12.9 is good??

Its more like 12.6 then goes to 12.0 up top. Probally could lean it out some but it seems like its making good power where it is.

A/F ratio is the ratio of the air to fuel mixture going through the engine. Duing normal driving the car will strive to maintain 14.7 parts air to 1 part fuel, hence 14.7:1 AFR.

LS1's naturally aspirated seem to like AFR around 12.8-13.2 although this is debatable, anywhere in there is good though. If it gets too lean(15.0:1) detonation happens and causes damage and if its too rich(11.0:1) you will lose power.

with your mods you want to run a solid 13.0 a/f ratio. your running slightly rich which means your losing a little power and using a little to much fuel.
