Since you are comparing the current engine and tranny operation with the previous experience, it is all relative. AND, with the adaptability of the engine and tranny ECU as well as the resetting of the adaptations of the ECU's upon removal and installation, I must ask the following. How was the car driven previous to the ECU changes?
Many people don't exactly rip their 850's every time they drive . . . well atleast not all of us :) As such, the engine and tranny ECU's adapt, requiring more pedal travel or acceleration of pedal travel to produce the same output, as well as tranny shift points. So if the car has been driven civilly in the last little while, and the ECU is pulled, and reinstalled, and running off the preprogrammed mappings, it will feel more powerful, and shift quicker. This is why many 850 owners reset their ECU's before racing their 850s.
Give your car a couple hundred miles to adapt. If it doesn't return back to what it used to be like with the same kind of driving you have been doing previously, then I would have the ECU read and checked for damage/alteration of some kind. Until then, I wouldn't panic just quite yet.
