The higher the speed the more the inaccuracy.

yea, I figured that.. I think on one burst I was surprised that I hit 120mph so quickly and later I read where the speed was limited to 113-115 and was wondering why I didn't hit a limiter.... I have the 245/45/19 tires on mine so I thought my speedo would register a little slow and according to my GPS it's about 1-2 mph slow at 65 or so.

I bought mine new and the only folks that's flashed my computer is my Ford Service Director buddy from high school "reflashed" the computer because of an issue I had early on, I wonder if
1. the "reflash" did something to the limiter?
2. since my car came with the 235/50/18s P-Zeros the limiter is higher?
3. the speedo is just off that much at that speed? (my dad used to "say there's nothing faster than a Ford with a jacked up speedometer")
4. I was so exited I didn't look at the speedo correctly?

also my Chevy C1500 has a limiter at 100mph, when you hit a hair over 100 it feels like someone turns off the ignition, is that the way the limiter feels on these cars?
