Mass Air Flow Sensor.

The MAF is a component of the intake system. If you replace the rest of the intake system and the MAF becomes the most constricted point in the intake, then a larger one will allow more airflow possibly resulting in more power.
Obviously, when enhancing a system, you work with the most restrictive component first and then work toward the less restrictive components. I haven't looked at the MAF on the 2004 F150 yet, but generally by the time you get to looking at the MAF you already have a fairly efficient system. With a fairly efficient intake system, power gains from continued fiddling are mostly felt at high rpm's when your motor is trying to move a lot of air. These types of gains are mostly desired by drag racers.

The mass airflow SENSOR and intake tube are two different things. The Mass Airflow Sensor is the unit that measures the ammount of air that is passing by it. If you were to put a larger intake (in diameter) then of course the sensor would read a larger volume of air passing by it. However, there is no sensor that is "larger" per se. That would be like saying you are going to install a thermometer in your yard that reads a larger temperature. It doesn't really make sense. Once you open up the intake (and exhaust) a Tuner helps to gain the most out of the "readings" from your mass airflow SENSOR and oxygen sensors, resulting in better performance.
I hope I clarified my confusing earlier post....
