The following is from another forum:
"Been a tech for Ford for last 14 years.
There is no way we can tell if the tune has been changed.
Resetting, over rev, and speed limit reached are stored, but can be erased just by disconnecting the battery for
15 mins.
If asked why the battery was disconnected, just say you left the dome light on, and had to get the battery
We can't prove otherwise."
