I have a 2007 suzuki grand vitara with the 2.7l v6
So far, I have installed an HHO generator and a volo chip. Absolutely 0 mpg gains, maybe even a little loss. Very frustrating.
From reading around, it looks like I have to install an efie before I am going to see any gains.
I ordered :

and

my questions are:
1 - why am I showing absolutely 0 mpg gains with HHO and the volo? Shouldnt I see something?
2 - should I use both the maf and the efie? should one be instlled and tuned before installing the other.
3 - on the efie install instructions it says to look for the signal cable by testing for the one that puts out about .5 v. if I unplug the o2 sensor, should that .5v come from the o2 sensor end or from the engine?
thank you all for your help
