Interesting. I guess the whole country, and the oil companies, have got it
wrong......

The moment you cross the border into Colorado with a turbo or a
supercharger, you car will cease to function..................

The manufacturer will state an octane rating for the elevation that the
car is to be operated at. There will be a footnote about changes to be
made if the elevation is increased.

>My DJ would have a problem on Super Colorado!

Since there are plenty of turbos and superchargers on the highway in
Colorado, I would say the prevailing thought process of less octane at
higher elevations is pretty much correct.

If you are passing through the higher elevations with a turbo then the
computer will compensate for it and you won't notice a lot of difference.
If you live there, your computer/engine combo will probably be different
than that of a person living at sea level.
