I'm using a Innovate Psn-1 wideband/bottle pressure gauge. I recalibrated it today and I'm still getting an average of 12.5 a/f wot on the motor. I don't have a data logger, I need one though.

Could the colder plugs have something to do with the change?

On a bigger shot I figured the 8's would be too hot and would melt.

I'm assuming It's something minor like the weather change or something. The earlier pulls I made with the 11.8 afr was in early spring/late winter. Idk the car has been running great all year so until I have it re-tuned I will just keep an eye on it.

Not sure of my fuel enrichment since it was remote tuned. I asked but they won't give me that information which is why next year I'm getting a new tuner

11.8 on motor and 10.8 on nitrous seems on the rich side. You need to read the plugs after a wot run done correctly. If your thinking colder plugs are causing the afr change, try putting your old hotter plugs in and see if you get the same afr of 11.8 on motor.
