TSB performance issue

I just had the TSB that required the ECU to be reflashed to correct the severe downshifting issue on some of the 2015 F-150's It seems to have effected the performance of the truck somewhat. Has anybody else experienced this issue? Also can you get the truck put back to the original factory programming. The service Tech at my dealer says no.

Give it time...the computer learns your driving habits and that gets erased when you reflash the system. Let the truck relearn your driving style and then see how it performs.

I had the newest of the two shifting TSB's done and haven't noticed any performance hits. However, that may be due to having connected to a trailer almost immediately for a 2000 mile jaunt.
