Not exactly sure but it seems like they raised the torque targets by a fair margin which massively boosted midrange performance based on the curves presented with a smaller gain in horsepower between 2800 rpm and 5000 rpm near the current power peak. The power already starts to taper off after 5500-5800 rpm anyway so shifting past that point is less beneficial anyhow.

Per the Focus ST owners guide supplement the peak power figures were achieved at 5500 rpm on the stock calibration.

It seems that this tune is focused primarily on increasing the available torque though.
