Oh, well since the government performed the test we know that went well.
It was on a few older vehicles and the test was conducted in 09. It actually showed the dirty or clogged filters gave better mpg, but the conflusion didnt mention it.
Since with the insight ima assist is partly based on petal position I am expected it to actually go up vs down. I pointed that out earlier in this thread and even included photos to show, but guess no one saw it?
