Posting these stock tunes I was able to pull off a 2022 E350 and off a 2021 E450. I looked for awhile on the internet with no luck and finally had a friend post the request on Facebook and got hooked up with another friend that had a couple in service they let me pull the files from.
I'm still looking for a 7.3L 6R140 F53 chassis stock tune, if anybody has one that would be great.
