In my experience a reflash will just bring the car back to base behavior. Admittedly, on newer cars, I have only had it done it on the transmission rather than the ECU. To me it seems like this could be a transmission programming issue.
IT doesn't mess the car up, it's just that if you drove like a boy racer, it might take a few drive cycles for you to feel like the car is in sync with you again.
Well, it depends... When you floor it, does the RPM change to indicate that the transmission is in another gear... just with a delay in getting the car to move? If yes, then it's engine management. If no, then the transmission isn't quite getting the message that you are in need of a change in gears.
What I would do is ask the dealer if any TSBs (technical service bulletin) exist for your car. Whether they exist or not, I would ask for a quote to reflash/ reprogram the transmission then engine.
I understand your frustration, and I hope we make some headway in this soon.
