Don't forget your old Chemistry course where PV=nRT. Boost Pressure P is a function of the number of moles n of air and Temperature. As you get closer to the end of the efficiency range, most of what you get is more T instead of more n. the n helps of course, but the T hurts. Presence and design of a wastegate, vs. no wastegate, and air flow capacity of the turbo matter a lot, and of course vary from one application to another. One model car may have a turbo that can do a lot more for power than it does in stock form, while another might be close to maxed out in stock configuration.
