That was a different vendor's TCU tune and thank you for the head's up. Keep in mind, I warned Steve NOT to install the TCU tune back then (even though it was free) due to what I felt was a lack of research and R&D. Moreover, I'd just watched Jeep and LX owners (with MB TCU's) go through the same thing a year or two earlier.
