Also has any tried the flashing or updating their 2006 325i with an 328i ecu software/update and will BMW still warranty it?

325i engine has 2.5 liter displacement, while the 328i has 3.0L displacement...
Flashing the car will surely void BMW warranty.
In the E46 era, the 325i was the upgrade of the 323i, while the 330i was the upgrade of the 328i.
Now I am confused, because I think they sort of downgraded...330i to 328i and 325i to 323i....and on both cars, the engine output also lessened. Weird
