This is my truck in the photo. I've been working with 5 Star tuning to R&D the process with HPTuners. Apparently there was a different to the boot loader. Anyhow, after sending the PCM to them you can flash via ODBII using their hardware...
Can anyone post the TSB PDF? Looks like it affects 5.0 trucks built from August 2022 - April 2023. Just posted today. Any more info would be awesome!
EDIT: attached it as a PDF as well.
