Unless you're saying AA makes a tune for the straight six N52 that drastically improves the midrange? Our E90 328i is just the family beater so I'm not going to bother modding it, it's a fantastic car I just prefer the new motor's power.
Exactly what I'm saying, I have the AA tune on my N52 128i, and it is a huge improvement over stock, especially in the mid range.
