Is there an power increase for my engine via software available? [V60 2015]
Yes. The simplest way how to find out is to connect the car to VDASH and see the Optimization tab (if the buttons are green, in means give SW modification is immediatelly available).
You need the ECM pin anyway.
You can also see the details thru VIN search (https://d5t5.com/search/YOURVIN) - yet it is needed to have the car connected to VDASH to detect all necessary SW numbers
