A mechanic at the dodge dealer told me that when any diesel comes in for warranty work, the first thing they check before starting any work is plugging in to the OBDII because most programmers leave a history.
2 years ago, I was at the fairgrounds watching a truck pull and the service manager from the dodge dealer was sitting in front of me. After a brand new dodge went racing down the track, I leaned over and told him he'll see that one in the shop tomorrow. His response was "he better bring his wallet, he left his warranty at the starting line." Don't think that driver could BS his way out of that one....
