I also drive a 3.5 EB and when we are in low octane states, I will always pay for at least 87 octane. I do it because the owners manual says to run at least 87. At high elevation most regular gas is 85 octane because a not turbo engine can't use the higher octane. My turbo does not care is I am at sea level or 11,000 ft, it always thinks it is at sea level because the engine just kicks up the boost to make up the difference. That is why my little 3.5 turbo can run comfortably going up the steep grades at high elevation. And contrary to popular opinion, I do not have to wind the engine up. It makes full HP and torque from about 1800 rpms unlike some engines that have to be run at 4000 plus roms to get power and torque.
