Sorry guys I have lots of questions about the engine inside my new 2007 328i Sedan.

What is the exact engine code for this year?

Whats the difference between the 2006 325i engine versus the 2007 328i? Was it just an ecu update or was the exhaust system revised? I wish the engine was as fuel efficent as my old 2001 bmw 323i (2.5 versus 3.0)

The E90 engine features valvetronice instead of Double Vanos or does it have both? I heard vavetronic is not used on any of the bmw m cars for high rpm reasons so it stays true mechnical valve timming instead of electronic nannys.

Whats the difference between the 2006 325i vs 330i besides exhuast and ecu? I just want to know the details on the changes and was the transmision gearing updated on the 2007 328i?

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

Acutally I wish the 328i got the same engine rated at 260hp like the X3 3.0si not just 230hp but it wouldnt make sense since the 2006 330i made 255hp.
