2007 550i tuning options

[Markus8291]

Hey everyone,

before I get scolded for asking this question, please know that I did quite a bit of searching, but unlike for 3 series (which I myself have) there is not much info out there on the N62 engine.

I'm trying to help a buddy of mine out who just recently bought a 2007 550i and I'm trying to help him out with his mods and trying to figure out what's out there. Obviously he's a lot more limited with his NA engine but still. Drop in filter and exhaust is about the only thing I've been able to find.

I'll be doing some coding for him tomorrow and scrapped together whatever info I could find (I've coded a bunch of E90's but no E60's yet)

Thanks for any pointers anyone can give me!
