Yes, it helped somewhat. Now I understand that what people call "throttle body reset" is only resetting transmission shift points (which are tied to a key) and in my experience after the car "learns" your driving habits, the problem are mainly related to changing 3rd to 4th, 5th to 6th gear.. too soon, so obviously when you are in the higher gear too early, torque is lower and the car just doesn't feel right.
So XHP "fix" helps somewhat, but after doing the procedure for resetting transmission shift points, the car definitely feels more "lively" and drives better without annoying early upshifts. I am really hoping that this behaviour can be permanently removed or coded out.
