Don't forget that the 325i and 330i have different axle gearing, the 330i's being taller. I'm real curious to see why (mechanically or electronically) the upcoming 328i has HP/torque rating smack in between that of the 325i and 330i.
Yea Voiding my warranty is a big fear of mine, that I is why I am going to do it (if anyone firures it out) when my warranty is up!
