The thing you're missing is the speed of the air at different points in the system. In a fat area, air will be moving slowly, while in a narrow portion, air will be moving more quickly.
Bottom line is: If the MAF is in a tube that's smaller than the stock location, air must travel past it at a higher velocity, fooling the computer into thinking more air is entering the motor than actually is (since it thinks that high velocity is in a larger tube). This could easily throw a code since the MAP sensor and MAF sensor are not agreeing with each other.
