Just took my Raptor in to get a Smog check here in Nevada and received a "Rejected Smog" result. Looks like it failed on the OBD Catalyst, Oxygen Sensor. The tech asked if I had disconnected the battery. I had not but did install the 93 tune although it has been a few weeks. He told me to return it to stock and run it for 50 miles and bring it back. Just wondering if anyone else here had a similar issue? Was it due to the tune? Did returning it back to stock allow it to pass?
