You would get better responses posting this in the Nitrous section. People are going to tell you to read the plugs instead of just relying in air/fuel ratio.

in my experience watching the air fuel is almost useless since they seem to peg RICH, whereas the wideband is actually more precise......

reading the plugs is a very good way of determining function watch #6 and #8 plugs close they will tell more than the rest since they lean out the worst.

11:1 is too rich IMO, put a big shot running that rich and you'll lift a ringland

nitrous doesn't need to be run very rich, you need to run conservative timing and run good gas.
