Yeah, I've seen similiar activity on other forums. They immediately debunk it as an impossibility with the standard "Show us the Dyno report", I've only seen one that has referenced the emissions.. which is rather odd since Ron has shown the emissions results on a number of his Youtube video's.
What I find of "real intelligence" are the ones that find the most inane bit of detail that is not specific to the topic and start chewing on it like it's an all day thing.
Give them fuel mileage data they can't refute and they focus on some non-relevant bit that has nothing to do with the post.
I think the ones I like the most are the "according to my physics education, this is totally impossible" responses.
Was talking to the UPS driver this morning, their switching to all diesel because of the poor gas mileage(winter blend). Explained to him about the above activity and pointed out my part in this and the vehicles that I have that "are not supposed to be able to do what it is they are doing".
He took note of the "Grooved" sticker on the side window of the 2008 Cobalt and the Gadgetman Technologies bumper sticker on the back and will be checking it out when he gets home... and hopefully he'll talk to the mechanics at his UPS depot as well.
