Taking Viggen to Colorado - which gas?

We're taking a two week trip to Colorado in our Viggen. I know gas has lower octane ratings in Colorado, and I know octane requirements typically decrease with altitude.
But the Viggen is supposedly turbo-normalized such that the T7 increases boost to maintain the sea level torque rating up to 10,000 feet. That makes it sound like the octane requirement for a Viggen won't go down with altitude. Viggens call for 93 octane gas, which is hard to find in many areas, and impossible to find in Colorado.
So to all of you high-altitude Viggen owners, how does the 89 octane "premium" gas work in your cars? Do I need to bring a few bottles of octane booster with me? We'll be going up to Rocky Mtn Nat'l Park and Vail, so we'll see 10,000 feet a few times.
Thanks,
Jeff J
