higher airflow = more power?

i keep hearing that when TII's have an SAFC and they put on like a new 3" TID they get like 3% more airflow. Does this have anything to do with power?

Yes.

Power is directly related to the gas flow rate through the motor. That is what turbo's, superchargers, and ram air systems do.

You're really putting too much thought into this one...

When you put on a cone intake, or an exhaust, you make air get into and out of the engine MUCH easier and more efficiently, making more power. When you put on a turbo inlet duct, you reduce the restriction at the turbo's intake, so the car can make more power.

So, the car is sucking in more air and making more power. The airflow meter sees the extra air going in, and outputs the data as such. Changing the SuperAFC's settings does make power, but it does so by modifying the fuel curve by altering the airflow meter's signal.
