When I first got my scangauge, I noticed my regens always started at 19 grams off soot. After the recall was done, they started at 22. Now, with the recall removed and the "original tune" supposedly back on the car, my regens still start at 22 grams. So, I think whatever tune my car left the factory with is gone forever. I was hoping it was stored somewhere and that it would be a true restore, but doesn't look like that's the case.

I wonder why my first one did the regens at 19.

My regen interval is not much different in any of the tunes, even with the extension from 19-22 grams.

There are only 2 main tunes out there (3 if you count the bad one).

Do you know the differences between the 2 main tunes (other than the 19 vs 22)?

I bought my car in May 2013, one of the first off the line. It was a great tune. Very few problems over the miles.

If you ask your dealer nicely tell them to tune it with OS Part number 12658788.

Thanks. I think they would have no problem doing that.
