My wideband was displaying 10.8-11.2:1 AFR today with a 100 shot.

From an engine SAFETY standpoint, should I leave it alone?

You should lean it out to about 12.5 to 12.8 on Nitrous. Set your timing at 25 degrees and start leaning it a bit at a time to get there . Then you can try bumping the timing up 1 degree at a time to see the mph results.

This is what the spark plug looks like from the dyno with the same jet I have in there now.

The burn ring on the porcelain is too tall indicating too rich. It should be about 2mm tall for ideal jetting.
Here is some good info . Check out the 10th picture to see what I mean
