Maybe I am reading this the wrong way, but I kind of agree w/ the dealer. And again, maybe I am misunderstanding you, but from what I am reading I believe your car is working properly.
When you start the car first thing in the AM, or 1st time that day, the engine is cold and it must be brought up to operating temps before you can "floor it" otherwise the engine and turbos are cold and it will "buck" for about 5 seconds or so until it warms up..
Now onto the "flooring it" issue... If you drive the car normally and do not floor it, the car should shift at its normal RPM's, prob somewhere around 3-4k RPMs is the optimum shift range for fuel efficiency. From reading your post, it appears your car behaves normally when driven normally... Yes? Correct?
However when you "floor it" the car is not suppose to still shift at 3-4k RPM range, that does not happen, nor is it suppose to happen. When you floor the car and keep it floored, the car will shift at redline in every gear, this is normal and the car is doing what its suppose to do. If your pedal is to the floor, you are essentially telling the car you want to drive fast, and the quickest way to increase speed is to redline shift.
You cant put the pedal on the floor, have the ECU telling the car "I WANT TO GO FAST" and then still have the car shift at the "economy / fuel efficient" RPM range. It does not work that way. If you go half throttle, the ECU shifts the car in the moderate RPM range. If you floor the car, the ECU tells the car to shift in the "high RPM range" because the quickest way to increase speed is to redline shift.
If I go jump in my car right now and floor the gas pedal, I can guarantee that the car will automatically redline shift in every single gear. This is normal behavior for any car. You cant tell the car to "go fast" yet still shift in economy mode. That is why the dealer told you the car was behaving properly when analyzing pedal location, speed, and RPM's..
Unless I missed something or took something the wrong way, your car is fine. And the dealer is correct, the tranny will adapt to your driving style bc the ECU records your activity and adapts.
If you want it to shift in the 3-4k RPM range, stop pinning the pedal to the floor..
