Yessir. Right now its like a fuel additive on my car and truck - added power only, with some add-ons I could fool the computer into leaning out the gas and increase fuel economy as well. Without going into a full blown lecture I'll jut say this - the Internal Combustion Engine (ICE) doesn't care what the fuel source is, its simply a mechanical device. It will burn gasoline, alcohol, hydrogen, if it is a gas or liquid and burns your engine will burn it. That said the stoichiometric ratios are different for each fuel source so you will need a different amount of fuel to burn for each setup. There's other considerations too, but I wanted to keep it short and sweet.
