Would the computer just compensate, or would the extra air in the tube mess up the preset calculations the computer has?
Regarding the air/fuel ratio, nothing would happen. The o2 sensors would allow the ECU to compensate.

The larger diameter would slow down the air flow and could cause a loss in power.
