Do you know what these cheat devices actually do? They retune the engine for better emissions at the cost of fuel efficiency or performance. So they actually could have the lower emissions, but it would mean they would miss a fuel efficiency target and the customers might not buy it. It’s not a magic trick or impossible at all - it’s just an engineering trade off.
