Ok, I didn't read everything about it but from what I understand your TPMS light is on, you aired all of your tires up evenly and it's still on.
This is because of a few reasons, the light will come on after a tire rotation because the sensors are not in their original position, and simply airing them up does not fix this.
The sensors have to be reset so the car knows there they are, on Fords I do not know how to do this.
On GM's you can put the vehicle into learning mode and re-learn the sensor positions. Fords, maybe you have to drive a certain amount of miles.. I don't really know, but I know some are like that.
What did you set the air pressures to? They should be most likely at 35 p.s.i.
Even a small 2-3 p.s.i. difference will trip the lights, I have seen it happen.
Since Ford told you it can be done by itself, it almost leads me to believe maybe one of your sensors just is not working. They should be able to test that out and see if one is faulty. Pretty strange that it came on after your CAI install though..
