which power programmers are best?

This is what I knew, and was trying to find out why it was being questioned in the stock tune.
There are thre things that effect fueling. You need correct injector information, you need your commanded air fuel ration, and you need to know the airflow. If the fuel injector info is correct, your commanded air fuel is what you want, but your not seeing it, you need to adjust the amount of air the motor thinks is coming into it.
