Thanks for the share ! I saw your post the other day, but don't just click on links without others trying them out first.
Just FYI, the ecomod bit is at 10:42 in the video, everyone.
I'm surprised that they admitted it actually works, since they had said earlier in the video that increasing your tire pressure is just a myth.

Well that's testable both ways. If increasing pressure doesn't improve mpg, than decreased pressure shouldn't hurt mpgs...
