Took the wheels and tires off the truck and pulled the programmer out without resetting back to stock.
No, neither one offered to re-flash. The local dealer just wanted to completely replace the PCM. I called the other dealership for a second opinion and they told me that they would only replace the PCM as a last resort, they were still sure it was the speedometer itself. I wasn't impressed. The local dealer kept the truck for over a week and just wanted to throw parts at it (a gambling habit financed with my pocketbook).
If I take it into another dealer and ask for a "re-flash" is it something they they would readily do, or do they need to run their diagnostic to see if they can justify it?
