I live on Denver area at 5280 feet, I have not had any problem with my set up as far as poor acceleration in mountains. I tuned the fuel Pac with the add ons I have installed and my bike runs great. In fact the top end has greatly improved. At speeds of 60 in 6 gear, the bike just zooms, then at 75 mph I cranked it on to pass and I was 90 before I knew it and didn't have to down shift! The stock version was a dog, yuck! I ride up in boulder also about 6800 to 8000 feet, with no loss in power. Just saying running a 07 Ultra
