I own a 2007 5.7 liter Tundra and am very interested in building a basic HHO system to gain some fuel economy without having to make any major mods to the ECU, MAP or O2 sensors. So far out of all the threads and posts I've read, you seem the most knowledgeable and seem like you have done your home work. Any advise on where I can get a nice set up plans to build my own HHO system ?
Thanks in advance,
