Toger,
I drove most of the way to Louisville and back to Waco at night after midnight. Traffic was very low and there plenty of places to open it up, but I still kept my speed down to about 70-75 MPH. What's weird is my GPS said I had reached a maximum speed of 84.5 MPH on the way to Louisvill, and 122 MPH on the way home???
I know of one occasion when I kicked it up to a little over 80 MPH to get around another vehicle, but I know I never went faster than that and surely not 122 MPH since I don't think the truck would go that fast even without the 97 MPH speed limiter.:wacko:
I think my GPS got confused I attempted a time adjustment and that may have caused it to nearly double my average speed during that one hour change.
