Their english isn't great; but I'm curious how they can claim those #'s with
just altering the o2 signal -- and "maintain smog certification".

I pinged a few people that bought them, but they all had honda's etc.. but they
swore it made a huge difference...

What kind of signal modification could it possibly make?
