Any flameable super heated (at room tempature) gas like propane, natural gas or butane does the same thing.

is this straight up water? or do you add fuel to it? if only water are you suggesting a 4% improvement due to the high EGT readings and resulting increased diesel fuel use you would have without its use?
i have found on diesels aside from the EGT control and tamed flame front (besides some benefit from thermo expansion) it is mainly the cooling that is of benefit but not exactly with significant MPG gains. what is YOUR secret?
it is gassers where water injection has tremendous potential. by manipulating fuel volume and or timing interesting things (MPG) can happen since a spark ignition engine under load is naturally on the verge of pre-ignition. like previously stated i would looooove to play with a CRX HF!

if you would like to see positive effects on MPG and power try propane supplementation!
I use tap water.
No fuel added to the water.
Unlike HHO I have no secret. Every detail of what I run is on the wiki, its not too difficult to figure out.
I wouldn't call 4% a significant improvement.

Water injection has little potential to boost FE on gassers.
You are better off with aero mods.

I already tried propane back in 2006 for boosting FE. It was expensive and in the end figured it was more trouble than it was worth.
But I plan on revisiting propane for short boost power.
