As long as you don't throw any codes, you're golden on inspections. When you get tuned for the dp, your tuner should eliminate the code from ever popping up.
I only had one guy ever do a visual check on any of my cars and it happened to be on my wagon (I'm fully catless). All I did was tip him a few extra since he was being a dick about it. Nobody else ever visually checks, all they do is scan for codes as far as emissions.
