Not using HHO currently...but have a DIY system. Might try the FS2-HHO since I have the HHO unit and it might be more sensitive to the use of fuel additives.
As far as I can tell...these dynamically adjust the air/fuel/timing in closed loop....over-riding the ECU to some extent....with the intention being greater fuel efficiency.
I'd have to see around a 10% gain for payback in 1 year though.
Do have an EFIE and know how to do sensor mods...just hate to start hacking the wiring.....
