If you dissassemble an engine and look at the irons and the housings you will see a few passageways that allow extremely hot exhaust gasses to move to other places of the motor besides the exhaust/turbo mani. The passageways lead to the LIM where they enter the LIM enroute to the ACV. Most people have long since removed thier ACV so sending hot exhaust gasses to it does nothing beneficial. All it does is heat the LIM and the charge air as well.

While getting to the LIM the exhaust gas is confined in the housings and irons and transfering exhaust gas heat to these pieces which is being absorbed into the material and also heating the coolant more.

By plugging that little passageway you are preventing the exhaust gas from going anywhere but out the exhaust sleeve where it belongs.

Make sense?
