I'm guessing the reason he said that is because once you go nitrous, the longevity of your motor deteriorates at a much increased rate compared to not. Even if you run wet shot direct port or w/e, there is still going to be more wear on the motor and it simply won't last as long as if you hadn't ran it. If it would have originally went 100k, maybe it would reduce it to 70 or 80k.
