I'm just telling you how the airflow tables work, if you don't think it's right you're still wrong.
Fueling is always based on airflow, the more airflow the motor see's the more fueling it's going to give. The way you have tuned the car is by fudging other aspects of the tune you get what you want, it can work sometimes but it is still incorrect.
If someone added a cam and it was too rich at part throttle you wouldn't start skewing the injector flow rate tables or open loop tables to remove fuel or add fuel, you would adjust the airflow tables to tell the computer that it needs to remove/add fuel. You do that by removing/adding a small percentage from the VE or MAF curve.
Tuning the flow rate tables or using the add vs rpm/time table to get the results you want it just fudging numbers and a hack way to tune.
