  "" idle circuit 11.5-12.5
  12.5-13.5 average at cruise under load
  Higher at WOT (13-14 momentary 15 right when you stab it)""

 What fuel are you running (E10, E85, etc.)

After a 67 mile drive of combined Freeway, highway and surface streets... here is the #1 plug
92 octane premium unleaded E10 There are a few stations around, very few that are ethanol free. I made it a point to fill up with ethanol free the last couple tanks before putting the car away last winter. Driving with E10 and ethanol free I can't say I noticed a difference in driveability but I did not look at the plugs after a tank on no ethanol gas either... The ethanol free is 91 octane. This is in Washington State. Most all gas in NW WA is E10.
