I think your all missing the point of his question. He needs to know is what I call "the corrected" altitude.

When we race at "THe Strip" in Las Vegas we adjust our jetting leaner and increase the total timing about the same as we would for Los Angeles County Raceway (Palmdirt Raceway). Because of the very dry air at both race tracks 4500 foot "corrected altitude" is correct. Las Vegas has a .25 second factor in our 11.90 index class because of the reduction in performance compared to sea level. 2200 feet might be the "actual" but he needs to be thinking closer to 4500 feet for tuning.
