Hello guys, I'm a new user on the site and I'm happy to be here. I just ordered a HHO kit from a local guy here in central Florida and I'm installing it on a 2006 Toyota Tacoma with a 4.0L V-6. Does anybody have any input on a ballpark MPG increase I may see? I understand that all generator are different but this one is supposed to put out 1 liter a minute. Thanks in advance!
