The whole point of the first post... getting back to that... would be to have the engine reading that the TPS is higher than it should be compared to the MAF signal. Higher throttle opening usually means more fuel, but in FI cars, the MAF measures the actual mass of the air being flowed, so the ECM assumes that the car is operating in a low-pressure area or a warm air area. This can be refuted or proven by the IAT, which determines temperature alongside the MAF's reading.

Together, the sensors provide information about how much mass is in a given volume of air, and the temperature of that mass, which helps to determine barometric pressure at the current conditions.

None of those things would be affected by a restriction in the intake tract beyond the MAF sensor.
