How can I implement a feature to change settings?
1) If you made the changes in only views then only export the view form your local development and import it in your production server

or 

2) If you added an new field in content type then goto admin/structure/features/create select the field from FIELD INSTANCES (x) (field_instance) and module will select the dependency automatically then add Name in GENERAL INFORMATION and download and upload it in your module folder and enable it and then follow the 1 point

Note: First try it on your another test development and then on production
