I think he lives where a properly designed fuel injection system can compensate for altitude......mostly.
Of course if you are operating on the ragged edge of being under-powered ALL the time there ain't much you can do when you go over that edge, for whatever reason.
The fuel injection system can't compensate for the lack of air density. All it can do is ensure the air fuel ratio is ideal, which the old non computer controlled carbureted engines didn't do so you had not only the loss of power due to air density, but the additional issue of the fuel air mix getting out of balance which made the problem even worse. When I was going through my aircraft mechanic schooling we had to learn how to mathematically calculate the performance effects of altitude and temperature on engine output, wing lift, and propeller performance. They're simple laws of physics and thus very consistent and predictable. As far as not being able to feel it....
