When i first ran my nitrous kit I was around 14.0 and I ran it like this for a long time with no issues, no pinging or knocking. I wouldnt recommend doing this to anyone else though. I now am at low 12's down to low 11's.
I always shot 12.0-12.5 on 100shot, adjusting the fuel jet for richness, sometimes the nitrous. I found that sometimes swapping a nitrous jet smaller makes a smaller change in AFR than the fuel for fine tuning. GL.
