From what I understand, the computer "learns" how you drive and adjust parameters accordingly; but I do not think it corrects for aftermarket upgrades. It is limited in it's adjustments.

This is how I understand the CAI. The computer does not know anything is wrong because the MAF meter does not sense the extra air. This is mainly due to size of opening around the MAF sensor. The MAF is calibrated for a certain size of intake opening and when you increase the size of the opening more air is allowed passed but the MAF cannot recognize this. In order to correct this, the tuner/calibrator has to adjust the MAF calibration for the amount of air that is now allowed.

Bill knows much more about this, I am still learning.
