My guess is no, but if anybody knows how to adjust it
I would love too know. I did a road trip this weekend
to the Jersey Shore and took along the GPS. I check
the speedo at 30,40,50,and 60MPH
speedo............................ gps
30................................... 32
40................................... 43
50................................... 53
60................................... 64
This is on an 82 300CD and I don't recall anything in the records
about the rear being swapped.
the tires are 195's as they should be.
Is this a normal tolerance or is there so,e other reason?
On a more positive note, this means my "corrected" MPG
is 32+ mpg
