Just checked my plugs today and cyl 3 was different from the rest
Well just normal checking of stuff under the hood today and noticed my cyl 3 spark plug was a little different from the rest.
The arc that goes over the electrode was black on halfway up to the tip, and the base of the electrode was pretty darkened to black also...
Does this simply mean my 3rd cyl is running richer then the other 3? Just wanted to make sure everything is kosher with this... Last time I ran at the track (saturday) My wideband was at a steady 11.1 mixture through the whole boost RPM band which I'm guessing pretty much on the rich side since I originally tuned at 12.1-12.5 (before it got cold out, and it was COLD at the track, 35F)

Its a possiblity that one cylinder is running slightly richer than the rest. It could be that one injector doesnt flow as well as the other three. Some advance ems's give you individual injector control to compensate for this.
