Nitrous on a 340 100 shot

When the timing is close to the ragged edge, the first thing to show signs of it, is the electrode. It will melt back the end of the tip.
I will dial it back another degree of timing and try a colder plug aswell and see if the results change much. Right now I'm at 33* and my best tune was 35* so I may be a little to high. Just didn't want to loose much power when NA but I suppose that's the tradeoff.
