I'm still new, but I have done a stupid amount of homework already. From what I understand the cloud tuning feature will not change the majority of your preset settings (the different effect sliders) It will change the sub filters within those effects to give you the closest thing to what the software deems the ideal experience. The only actual slider I ever notice change when I cloud tune my settings is the foundation force feed back slider. The rest don't move. Hope that helps. Someone else with more time with the wheel may be able to give a better answer.
