Good question. I keep meaning to address this. My rear tires are 26" diameter, rather than the stock 26.9".
26"=777 revs/mile
26.9"=751 revs/mile
I think 26/751=3.46% difference
As I passed the mile mark I saw 173 mph readout vs the 167 clocked. I would like to know from you physics heads and ECM techs, if the diameter of the tire makes this difference 6/173=3.46%? Or is it something else? Like the 4.10 gears.

I looked at your profile, Its a good chance you could get 190mph, you have about 300 hp more than me.
Tommys supra makes 1200 hp and I heard he got 228 mph that weekend
