Is it really worth the time to try to install one on my truck. I get around 14mpg. If it really works where can I find a diagrahm of ho to wire it. I think I know if it is the same as electroplating but want to be sure. Just not sure how it regulates how much hho is made in relation to amount of throttle. Does it cause long term damage to the engine. My truck has 185,000 miles on it. Could someone would please let me know .
