anyone hit the top speed limiter ? I heard it was set around around 115 mph. Saturday we did the Mustang Rally in Portland. Of course we got lost, more than once and had to 'make up' some time. I looked down during one particular long, straight stretch and saw we were up over 118, and didn't hit the speed default. I also heard it was set at 115 because of the u-joints in the 2005's were different design, as in not bolted together. My 2006 has the newer style ? Different top speed limit ?
