I'm going to change my trucks OS to a 2009's OS and was wondering what the proper order for reflashing the ECM & TCM is. Hopefully the only change was the A4 to the A6 between 07 and 09.
I'm also convenced that the TCM's shift points are somehow affected by MAP. And we don't have any tables to adjust things. The Varible Cam timing really mess's with the 6sp tranny.
