might be a little different but I had the same thing happen during my trip to yellowstone last summer. Went from right around sea level to 9k feet. Truck ran like a dog, thought I was going to be stuck in Montana... So no some 22re's do not like high elevations. ![Smile :)](https://board.marlincrawler.com/Smileys/marlin/smiley.gif)
Hope mine doesn't. That's where I'm going in July.
