Tom (from Focus Power) has been providing Remote Tuning for the community for a long time. I am not sure FSwerks does remote tuning on home made kits.
If you feel more comfortable getting a dyno tune you may be able to ask around the community to find a reputable Focus tuner in your area. I am fairly lucky and went to McNews Automotive in PA; another long standing Focus tuner.
