These plugs were put in when I had the re-ring done in January 2004, so they've been in a bit over a year. I'd say I put 12k on the car since then. When I had it dyno'd the car was running 11.5:1 up top at WOT. The car gets soot from fuel on the back of it at track events so I know it's a bit rich at WOT. Take a look at my plugs... is this "ok" or should i get her tuned? I was wanting to hold off on the tune until I got a cam.
