Looking at the video you posted, it looks like that person has applied a custom HP Tuners 1 BAR speed density operating system. He then is sunning the tune in opn loop and has access to a multiplier that can lean out or richen the VE table.
The tune you have does not have access to that table as it's only available with the custom operating system. But you could have access to lean cruise, that is not active on US vehicles, but can be turned on if I dive into the XDF and define the parameters.
Before we get to that, we need to make sure your fuel trims are somewhat reasonable. I would use PCM Logger to log them and make sure the Long Term Fuel Trims (LTFT) are between 0 and -5. If they are not, there are ways of using the fuel trims to tune the VE and MAF tables.
