LOL @ Kenny &
My car isn't tuned either, the N55 midpipe is dealer approved/under warranty. It's fast as hell anytime of the day in any circumstance
When I had my E90 M3 for a month I desperately wanted to trade it for a C63...
,
I remember driving a 997.1 S (355PS) , a very smooth and relatively torquey engine compared to the S65...A 3.6 B6...Just a NA6...Übermotor compared to the S65 imo....
Cheers
Robin
