Probably not real accurate but log slip. Even with the stock tune I saw a bit more slip before I added the Transgo. My truck wasn't tuned much before the trango and it was only a small tune. Not more then a 1900us and timing tune for sure.
I can see if I still have those logs, but from memory at WOT I would seen some slip up to 200 before and after it was only 6. That was in 3rd gear and up so the converter should of been locked.
