Please read my Plugs
My wideband says 12.5-12.8 on NA. On nitrous it goes to 10.8-11.2.
Br7's, 93 octane, with 116 in the stand alone at 58-60psi.
Plug on the left was 14 degrees 73/40 jets.
Plug on the right was 73/38 jets, was suppose to be 14 degrees, but looking at the log it was actually 15 for most of the run, then dropped to 14 at the very end.
I can clearly see the timing mark on the left plug. Still needs less timing right?
I can hardly see any color on the white porcelain?
I was thinking the rainbow color indicated heat too. Would going to br8's help this? Or is it a result from the fuel mixture?
NGK tr55 is the stock plug. br6ef is non-projected and a little bit colder. br7ef is good to around 175-200 shot and any more than that you go up accordingly.

I've been reading a lot about plugs. On article said- If the plug is too hot, the heat will actually clean away the fuel ring. Might be whats happening on these Br7's
