OP what OBD2 tool are you using to get this information? I'd like to try it out as well. Also, when I'm using cruise control, I have small "hiccups" where the tach will bounce less than 100rpms up, the car will feel for a split second that it has lost power, and then settle back in. My dealership told me this is normal, however it's only been present AFTER 12b37. I have talked to Ford Customer Service about this and it was escalated to my dealership, however, the manager at the dealership is the one who told me it was normal. I have since stopped using cruise control because it bothers me.
Once upon a time I had:
