The SAI is an emissions control device and only runs for a very short period at start up. Apparently this is only in North American cars and doesn't exist in ROW cars. It can be deleted by flashing the ECU but the file is different for tiptronic cars than for manual cars. It doesn't seem to affect the performance of the engine, only the emissions at startup.
