I will continue to used 87 even at higher elevations.
This should be an important take-away for anyone running an EB. Use minimum of 87, even at altitude.
With NA engines, you can run a lower octane (85 in Colorado) at high elevation, as the lower air density effectively make your engine "part throttle".
With forced induction, the intake air pressure is relatively constant (within the turbo's parameters). In fact, at high elevation the turbo works harder (higher pressure ratio), which means high intake air temp. More important to never run lower than 87, even in Tibet...
