Increased MPG

[6pack]

That's what I was asking a few posts up. I take it you can adjust the tune for it then.

wpage, you lost me with the first part of your post. If the input of hydrogen/oxygen causes the O2 sensors to read lean, which in turn casues the pcm to increase fuel, wouldn't causing the sensor to read less oxygen make it not ask for more fuel? Which puts us back to the original situation of using less gas. I also don't like this type of bandaid fix. I would prefer to be able to tune for the increase. But if it works it works.

I heard back from the one company today, thermo1. They said they have no problem with the O2 sensors.
