Hi all, I am a newbie. The more I look into HHO drycells or wet the more confused I get about it. I have a 99 4.0 Cherokee and think I should go a drycell route. I think from what I have gathered on the internet I need a 2-3lpm unit with 16-21 plates as well as a FS2 chip which I guess fools the computer. Can someone start putting me in the right direction. There are EFIE's , O2extenders ,bubblers, check valves and on and on stuff I am trying hard to comprehend it all and getting more lost in the process
