I emailed my stock tune to MPT after the update and the tune does in deed need updated. I paid the $25 and am waiting for the updated version to come back. I can't imagine there is much time involved in adjusting it since the fee is only $25
I just got the update from my dealer as well and sent the $25 to MPT, re-read the new stock file, e-mailed it to them, and re-installed the MPT tune. While I was at it I finally had them remove the auto start stop feature. This by itself is worth the $25 I have come to realize. They said that the speed limiter is automatically increased. I had been using the 93 PRX tune and went with the performance / tow tune for this install. I would describe this tune as while still very powerful different than the 93PRX. She feels smooth as silk now. I'm not sure if it is the update or the different tune.
