Absolutely, more air + more fuel = more power. But the beauty of higher altitudes is that you can make up partially for the lost air/fuel mixture by running more timing advance. With the lower absolute cylinder pressures up here, cars are much less knock prone. Basically it just means that turbo Subarus suffer less from "altitude sickness" than normally aspirated ones.
