2010 E63 Performance pack?
Picture of my car included for fun





For WIW, I had a 2011 without the P30 and with fairly inexpensive tune from Eurocharged I had the same horsepower as the the P30. I never really felt I was missing out on much without having the LSD. However, you can always buy a Quaiffe (spelling) aftermarket LSD and have it installed for a total of less than ~$2500.
Hope this helps.
I always change my oem plastic idlers out with billet, as the MB idlers fail a lot.
