I've had my f250 6.7 for 2 months and recently it seems to be regenerating every 75 miles. Very annoying and killing my gas mileage. Installed dpf and cat delete pipe and I'm getting ready to install the xrt pro. Hopefully all works well. The worst part so far was pulling off the rubber hangers from the dpf/cat. There was a lot plug connectors and one hose connector, all easy disconnects.
