I live in Oregon and will probably retire in 2 years. I had California emissions when I got the truck but it disappeared. What kind of testing does Arizona do in casa grande az or surprise az . Oregon doesn't test diesels. I have clean efi live tunes. What am I in for?

They scan the vin look under the hood, put the truck on the rollers, probe in tail pipe and have you rev it a handful of times. my 2003 passed with a hypertech performance tune on it.
