I am confused, are you saying that getting the software flash will sorta work or stop working over time? If you have the flash then you have the flash. Any and all software updates will take into account the M performance software and include that in the updates.

Your argument that a care looses HP over age does not make sense. If your ENGINE is producing less Horsepower due to age, you will have less HP. BMW is not going to change or create a remap of their software to constantly give you the same HP off that your BMW had when it left the factory. I have never heard of a car company every doing this. If you do in fact loose HP as the engine ages, you will still have more HP with the M Performance flash, than with the base flash. Loosing 10% of 440 vs 400 will still produce more HP over time.
