Sorry but this is really difficult to understand due to the language barrier.

I can understand that you have poor acceleration but do you mean that you are getting 14L /100km at 120km/h? Or does you mean you have an average of 14L/100km and your car will not go faster than 120km/hr?

Have you check for engine codes? ODB-II codes.

Might be your MAF (Mass Airflow Sensor). You could unplug it and see IF the engine runs better. They do go bad. Air filter Ok? Spark plugs, ect?

From what I can see in your video, you have the transmission in the Manual mode, which means the trans won't downshift if you press the gas pedal to the floor. This will give you bad acceleration. Leave the transmission in Automatic mode...
