Turbo motors do a little better because there are based off of boos pressure, rather than a fixed mechanical equation like blower speed and rotor rpm. Corrected numbers are skewed for both, but more so turbo cars.
Like mentioned, everyone at elevation is in the same boat. Turbo cars less so, but you can pulley down blower cars a little to offset, but it creates more "drag" from the blower. For a turbo car, it is still going to hit the desired intake pressure, but is compressor efficiency comes into account for power. I supercharged car will make physically less boost at altitude (for non-waste-gated set-ups) on a given pulley arrangement. |

In my experience, modern turbo cars do make more boost at altitude that they do at sea level. One of my previous cars was a Saturn Sky Redline. That car stock made 3 or 4 more psi of boost here vs. what stock cars were making at sea level. The PCM limits torque output. At altitude the car is making less torque so the PCM allows for a little bit more boost.
