I do think the unit works good. I just need to do a more perminate and cleaner install. I couldn't place it in the plenum because the of the pressure provided by the turbo. I need to either build a venturi or buy one. The venturi that comes with the unit is not a true venturi, more like an injector that places the gas in the center of the cold air stream. The unit needs a vacuum to pull the hydrogen into the engine. I also didn't get teh right water. I grabbed the drinking water instead of the distilled. That may be where the larger amount of rusty water is coming from.
