first service makes car faster??????
im new to the forum, just got my new 2008 e92 , m3 coupe.
my dealer is not too savvy when it comes to Ms, however i heard that my car has limited power and when i goto my first service appoinment at 1200 miles ,they will tune my car to have more power and go faster.
i heard about this m tuning from a few people.
is this a myth or true?
