Long story short: the effect was very well noticeable, shifts were mainly smoother and better timed than before.
Maybe there's something similar related to the chip, so that it accumulates more and more information that hamper performance?
Just a theory, though...

Erasing the parameters to allow the car to relearn is one thing and I agree with that.. on our cars disconnect the battery for 10min and then the car can relearn.
As for the EPROM needing to be reflashed every 5 years is kind of funny. I would say it is marketing at its finest.
