check out this plug... this plug installed in staging lanes. 1/4 pass. shut down and removed on return road.
Total Spark (via log): 9.0 deg
Wideband: Showing 9.7-10.3X AFR
gap: 0.030"
plug: B8EFS
I get the idea more spark/less fuel needed. comments?

It has ran best times/et/mph w/the 78/44 combo, that resulting in around 11.4:1 AFR.
My wideband was showing excessively rich AFRs and I didn't believe it, but i guess its right.

Either reduce fuel pressure slowly or pull fuel jet or if you are comfortable with more power and your chassis tune can handle it add more nitrous jet.
I would for sure get it leaned out a point and a half at least, running rich with nitrous is waaay worse than running lean.

Your fuel ring needs to be about half of what you are showing, especially if you changed that plug in staging. Like others mentioned, keep the timing waaaaayyyy low until you get the fuel right. As you add timing back in the fuel will clean up but don't do it that way for now. I think you have a good grasp on the concept so just keep reading and listening and you will reach your goals.
Awesome A++ advice in this thread.

Both color and how high it comes up on the porcelain. Had you not cut away the threads that would have been a first indicator of excess fuel.
