US cars use MAP; we don't have a separate atmospheric pressure sensor. If they were the same value then they would also both change to vacuum and boost, but they never do. Atmosphere is always fixed. Maybe they include it so someone could get a rough number of relative pressures as a calculation difference against atmospheric pressure. I don't know.
I don't entirely understand this statement. Maybe a tuner knows. Maybe the CARB tune is entirely MAF based. I don't know.

That makes much more sense than the atmospheric pressure reading exactly 1 bar, especially at that altitude. I forgot about that point.
