Just took my car (3.0 with twin Webers) to the Alps up to almost 3,000 m (9,000 ft). Thanks to a dual O2 sensor setup, I was able to keep an eye on AFR-values. Idle AFR dropped from ca. 12.5 at sea level to approx. 11.5 at altitude. Unless you are doing hill climbs, you will hardly notice the difference when driving the car on mountain roads. Of course fuel economy will suffer somewhat, but you can safe fuel going downhill again
