Stephen and Omar at Velos said that's the way it's supposed to work. You have to reprogram the ECU back to factory, then drive it 1-2 days, and bring it back to be tested.
Needless to say, I wasn't happy about that news. I did a ton of research before choosing a tune, and never read anywhere about the tune breaking emissions testing.
I suspect Dinan would still be emissions-legal, but then again it's not as powerful a tune. So I guess it's whatever is most important to you?
