I have 8000 miles on my '98 GTS with filters, tubes, snake oyl rear assembly and decided to change the spark plugs. I pulled them and looked at them under a microscope and was amazed how clean they were. With the naked eye they were perfect , but magnified they had some residue on the electrodes.
What I did notice was how white the insulators were. They had no tan color to them at all except in a small spot on two of them. From the looks of the insulators I would think that it is running too lean. The car runs great, but it seems like it could use some more fuel from the looks of the insulators. Does Roe's fuel management allow you to adjust the fuel flow? I wonder if you would get more power from this and how much.
