Ford dealers man ... much as I don't want to think it, SMH. But don't give up, it's important to find a good dealership, even if it's a little further away. And if you can't find a Ford dealership, look for a standalone Lincoln dealership (much rarer unfortunately, but can be found). My Ford dealership isn't the best, but generally they are pretty courteous with diagnostic fees & such, I have to give them that. Never had to ask them for a calibration update, so don't know what their response would be, but I am sure the charge would be minimal, especially if I brought it in for another service and simply asked them to check if it was up to date.
