That was one of the many benefits of the typical fuel injection system (mechanical and the modern day electric) in that altitude should not make that much of a difference as say those with carbureted engines. The many sensors used by the basic FI system makes adjustments accordingly.What about elevation? Doesn't that play a role? I'm at 5800 ft. (colorado)
When I use to roll with my local VW Club way back when, we would sometimes do weekend trips up to the mountains (9000-10000 ft elevation) and since most of us had single and dual carbs, we would have to make stops to adjust the A/F mixture (sometimes timing too) as we got higher and higher. And then do the reverse when heading back down.
I know that typical premium unleaded around here is only 91, where as lower elevations sell 93 as their premium unleaded.miscalibrated butt dyno...good one! LOL! Willy
As for the octane, I run 91 in Jiggy mostly because the CRX fuel tank is small enough to where I would only be saving about $1.00 (USD) if I went with the 87 octane. :^)
The Volvo, with it's 20 gallon tank, usually sees 88 or 89 octane since there is no real advantage in running anything higher (the engine is a low compression engine mostly due to the Turbo).
