To set these cars to a ready state - you need a few drive cycles (see link below). Most people hit those marks in their normal drives. It's not about the amount of miles you put in - but more about completing actual cold start drive cycles.
It normally doesn't go out of a ready state unless the battery is being removed or cleared with a hand held of sorts.
I don't know much about tuning, but does flashing the car cause it to reset all the sensors and go back into a "not ready" state?
