Hi guys... I have my 2007 WR set up for 4000 - 9000 feet of elevation here in Salt Lake (4500 feet) and it runs like a champ. Next week we are heading to Ouray Colorado to hit some of the old mining trails. They start at about 7000 feet and top out around 13000. Do you guys that are "in the know" think I need to rejet before I go or can I simply adjust my Idle and air intake when I get to some of the higher elevations? Thanks for any input.
