That's where the turbo is working the hardest. With cars, the turbo is working the hardest at sea-level and is engineered go give max boost at SL, as you go up in altitude, it tapers off due to loss of atmospheric pressure, like NA.
Or in simple terms, it's like the car-turbo is already at 14,000 feet when it's at sea level. They don't design car turbos to deliver constant power as altitude increases.
Now, you could theoretically make a car turbo work like an airplane turbo, but in practice, no one really does that outside of some unique racing applications.

Believe me, I completely understand that all IC engines lose HP at altitude. But I am also fully aware that a turbo car suffers much less than NA.
