Havent had much time with the car this week, but did take a cruise out in the country, about 25 miles mostly cruising at 3000rpm with alot of stop and go and a few wot blasts. Still on the 110/93 mix and using champion RC9YC plugs. When they start coloring up i will lean the T slots at that time and see if they clean up at all. Engine ran fantastic with very good street manners whole short trip. Only pulled 3 because they all burn the same except #7 which is on the far left.
