I have reached the conclusion the NHRA is assuming that the boosted cars will be retuned when changing tracks, meaning that the owner will "turn up" the boost for a high altitude track, or decrease boost when going to lower altitudes.

On both occasions when I have kept the same tune and boost level, and ran in Denver and Kentucky at about the same temperatures, the difference has been about one full second, or a factor of about 0.93. That is almost exactly what NHRA says is the N/A factor.
