Contour Enthusiasts Group Archives Forums General General 109 mph gov on 95 SE

I was under the assumption that when you change your overall tire diameter, it throws off your speedo. I was also under the assumption that cutoff got it's info from the engine rpm. Therefore, it would say 109, but rpms would still be correct for cut off. It sounds a little silly to me for the cutoff to get it's info from the VSS, but ok.
