Warning! Nitrous Air Fuel Ratio
It could also be something with the wideband, but that is crazy lean.
At least 50 years of people going fast with N2O have set up accetable A/F ratio's for certain setups. These years of experiance aren't just shots in the dark. They come from experimenting and blowing up parts mostly the latter.
Lean is mean is a general saying. It should not be interpreted as "run as lean as possible to make the most power."
