Some of you know I bought an 07' 2500 4X4 6.7 last week. I'm taking it back to the dealer on Monday for window tint and a sprayed in bedliner that I negotiated into the deal. While they are at it I told them I wanted them to perform the updated AU flash. As far as I can tell, mine is currently at the AT level as there is no upgrade sticker on the core support, the PCM sticker has the AT suffix and I doubt the tech had enough time to check and update all the trucks on the back lot.

So far 300 miles and everything is great (as it should be of course), but my question is should I press for the updated flash even though I have no problems or should I wait? My gut tells me to go for the update in an effort to eliminate the potential for problems, but as I grow older I subscribe more to the, "if it ain't broke don't fix it" mentality too.

What would you guys do?

 

It may have come from the factory with the at software,I think if it were mine I would have it checked and updated if not at the at level.
