Some NAM member have been quoted some rather high install times by their dealers. I did a little web surfing and found that the "official" install time for the JCW Tuning Kit is approx. 2 hours for US Cars. For See http://www.minipeople.ru/images/PIDoc22654.pdf
Hopefully a copy of this document will allow NAM members to get their dealers to "re-look" at their estimates and give more reasonable install rates.
FYI

 

Mine was installed for a flat $200 (the dealer's shop rate is $102/hr) and when I picked it up the tech told me that after this (his 2nd R56 Stage 1 install) he'd love to do them all day no problem.
