I recently changed from power fc to link and was worth every penny! Went from 520 at the fly to 540 at the wheels with same boost pressure! So much quicker! Main reason i went for link was the knock protection and logging. If i go out for a drive i can quickly download the logs and see what’s going on. As for scatter that is a problem with the link but you can get an aem trigger disc for the cas which will clean the signal up and is only about £30. I also now have a tablet dash display where i can see any parameter i want without having gauges all over the dash.
