Plug read

[Jengel451]

I suck at reading plugs. Anyone have thoughts on this?

Straight out of the box?

Back off the timing

Thanks. Sort of wondered about that so I'll give that a try. More detailed info: 383 9.3:1 92 Octane

Plugs: NGK BKR6E-11 15 initial 35 Total Hyperspark controlled by Sniper 2. Gap .043

Once the engine is up to operating temp it misses at low idle up to about 1500 RPM light load. WOT it breaks up around 4500.

I'm going to back off 5 degrees across the board. I'm also going to close the gap up a bit.
