I have a 2010 Tundra LT 550F. I ride in high country at about 3,000 feet several times per year pulling a heavy loaded sled for 15 miles at a time. Sometimes the snow is pretty deep pulling the sled and other times it is a fairly well packed trail. The rest of the year I run in elevations of 5-6 hundred feet. I never have any problems but am I in danger of burning my machine up with factory jets installed? Does the higher elevation use more fuel and oil or less fuel and oil than the lower elevation?
My Tundra does seem to require a lot of warm up time with the choke in the half choke position at the higher elevations but then often times it is 25 to 35 below zero at the time.
