In a nut shell, thats what your O2 sensors and MAF sensors are for. They are constantly measuring the air intake and sniffing the exhaust mixture for the proper fuel air ratio which will properly compensate for temperature and pressure. In the old days with carburetors, if you were going on a trip to the mountains, you would turn the mixture screws in a half turn to lean the carbs out a bit. Then undo do it when you got back.
