You should be fine. You might have to adjust your idle mixture a little when you get up there. I rode a 98 tdub up to 13,100" and thats with the older carb which is more sensitive than the newer ones. It ran pretty good and started sputtering around 9,000-9,5000 feet but kept running over 13,000". If you are going to ride at 9,000 plus most of the time i might consider it but other than that i wouldnt mess with it.
