My buddy is over here trying to update his Smarty Jr. on his 07 5.9. On the back of his the first few letters start with SJ6..and a bunch of other numbers. When I check on Mads website, it shows a euro version for a 07 6.7, and on the SJ-6 it says 2003-2005???

Will something go wrong if I use the 03-05 link on the website???
