Their is a recall notice going out for 2011-2014 F250-F550 6.7's. You can look up your vin on the Ford site now and see it. Recall #14E03. I think it has to do with emission's.
Thanks for the heads up! The letters will be coming out on the 26th, so this gave me time to set up an appointment before the rush. It's a fairly straight forward reprogramming effort. No parts will be required.
