Not quite true. EFI injects fuel at a much higher pressure differential than a carb, and thus achieves much finer atomization. What is true, though, is that the longer path from fuel introduction to intake valve on a carb setup provides slightly greater time for evaporative cooling, and thus possibly slightly higher charge density. But the overall point remains - with identically configured intake systems, carb and EFI will produce almost identical peak power within the margin of error.
Of course, one of the great advantages of EFI is that port injection allows much more flexibility in intake configuration, which can and does yield benefits in mid range performance in particular.
