This is the second time I have my car out tuning on nitrous. I'm running C16 in a stand alone. Last time I sprayed, my AFR sat at around 10.8:1. I'm usually constantly 11.8:1 WOT on the motor and 10.8:1 on nitrous. Now I'm 12.5-13.2:1 on the motor and 18:1 and up on nitrous! My idle and normal driving is still the same around 14.7:1 stoich. The only thing I've changed was the plugs. I've went from b8efs to b9efs. The car doesn't seem to feel any different than normal under normal conditions and wot.

Anyone have any ideas? I was thinking maybe I leas fouled the O2 sensor but if that's the case why does it seem to function normally under normal driving and idle?
