BIL tried to register his deleted 2008 RAM in Arizona and was told to remove it from the testing station, when they looked under it with a mirror, and opened the hood to see blocked off ERG connection points. I told him to keep the items removed that the seller gave him when he bought it. When he sold his house in Ohio he dumped the stuff.
Bingo keep all the parts! If I owned a newer diesel that's what I would do, have a delete done if it's giving me problems and I would keep the old parts around if I had to restore it back to factory condition. Just my thoughts.
