heat and elevation (colorado or long island?) will be in play with Turbo cars. In general anytime air intake variables that effect volume and temperature change it will have a greater effect on turbo cars than NA cars, simply b/c the idea of turbo cars, to suck in more air and add more fuel to create higher hp, uses much more air than NA cars.

Also,high temperature will also effect the intercooler's core temperatures and cause the temperature of the air intake at the throttle to be higher than preferred, though the use of intercooler is still preferred in that case. I'm not quite sure when the heat soak will come in effect and be counter-productive to the alternative of not having a intercooler.
In a way, it shouldn't matter if the car is NA or FI. At the end, power = air & fuel... On the other hand, FI might be more prone to high temp due to air charge temp going up (as you also mentioned). But then that can be fixed with bigger/more efficient intercooler.

At high elevation, NA is stuck with what it can suck, whereas FI can increase the boost (again air charge temp problem).
