The Hydrogen works guys. Look at the alternitive fuel forums. About 60$ in parts and some labor a little bakeing soda and water.
I've tried it with my edge on and it doesn't show the mileage gains. I don't know why yet. With the edge off and the hydrogen on its about like level one on the edge though. Look in my gallery. Don't use just stainless only you have to have the copper for the negative or it doesn't work. I don't know why yet.

 

Stainless is not as conductive as copper.

I don't think it is the conduction but something else that is affecting the process.

 

Copper gives of negative ions much more freely than stainless. Stainless is an alloy, and therefore has a chemical bond already in place. Hence why stainless resist corrosion and oxidation, unfortunatly copper does not resist oxidation in anyway!!

It's a timeing thing. Hydrogen advances the timeing because of its faster burn rate. With the edge or other boxes they advance the timeing already and then advance it more with hydrogen and to much advance. Did you get the advance in that?
Try it on your truck and see what happens.
