Ok so I have a 21 plate dry cell hho generator and have been using koh as my electrolyte. I have my injection point on the back side of the intake filter box is there a better spot to inject the hho? And has anyone had any luck with efies? map enhancers? or o2 extenders? I am very interested in seeing how many mpg I can get out of my jeep using HHO.
