I'm glad you are willing to test it too, but am skeptical about anyones ability to be swayed at this point.

I will say for my own part that I will have a lot more questions if you do show a gain, as such a gain still needs to be satisfactorily explained so that it can be repeatable, but in the end I will always defer to empirical evidence over theories.

I'm sure you may face numerous questions from other parties if it doesn't work, asking to introduce more variables without controls and any failure to comply will be sufficient to not change their perspective. But there needs to be a way to compensate for any tuning beyond hooking up an hho device (i.e. ignition changes), you cannot assume your pre-hho had the benefit of such efficiency tuning and any gains might not be the result of the hho in that case, presumably you know this however.
