My mileage computer still seems to be accurately telling me how bad my fuel mileage is.

Uhhh... It generates water into Hydrogen. Hydrogen being mixed with oxygen is very flammable. Suck it into your intake and you have fuel.

BUT. If you don't use the right mixture combination, it can actually hurt your fuel economy. So tuning is a must.

the one i currently am experimenting with is working on my dually. i will transfer it to my denalli soon. most situation tunning is not required for the unit i have. it does not generate so much that it requires more tunning than the fuel trims can compensate for. it is a true on demand. it does work. i was actually able to light the hyd. bubbles on fire when i submerged the unit be installing(small unit). so far my dually looks like a 4+mile per gal increase.

oh yeah, I've heard about those... I was reading a website called water4gas a few weeks ago and it grabbed my attention for a little while, but then I just thought it was a bunch of bs, since it Guaranteed double your mpg or something like that.... So I guess it really works then, eh? Where can I get one, or would I have to make it myself like the website said?
