Pulled my plugs after I got home to check em out. (Im going to send the chip to Rick to have him richen it up a full point across the chart.) Anyway I have 3 plugs that have some carbon tracking on the white insulator surrounding the electrode. This should not be in my opinion. Im running TR6s at 035. Anybody else have this? Im going to dyno again in a couple of weeks after i get the chip back. I was thinking of trying the stock plugs-Im not that happy with these. Also looks as if the tip of the plug is off center of the electrode on some of the plugs. Lyle
