I tuned a 2017 challenger and the dealer did a reprogram for a recall. They flashed it with a different OS. Do I have to read and relicense it to put the tune back in ?

you shouldn't even try to put the tune back in.
You should just read the ecm as it sits, license it as it sits and use that file as your new base file.
Doing it any other way is NOT recommended by us.
Ok thanks. I was going to use my original tune as a compare file
yes
