Surprisingly, I found a 5 position switch on the fly switch hidden behind the dash of my 6.7 after owning it for a year. In this video I go through some of the tests I did with the different tunes, show some different driving clips, and share my thoughts on the newly discovered switch.
If anyone has some other ideas for simple tests I can do to get more data on the different tunes, let me know in the comments.
I still have no idea what company did these tunes or where the truck was tuned.
