I can say after reading through the hardships in "fighting the computer" has got me thinking of converting mine to carburetor. I have a 350 vortec...love the power and acceleration but if I want to run a lot of hydroxy then I would sacrifice the computer controlled induction for a carburetor. Won't be hard to do since it's small block chevy It would be too bad to see that vortec induction system go...

About all you'll lose by going to carb in that Vortec is how easy it starts.  All of the cool stuff is in the heads.  But, if you insist on keeping the nice looking intake system, you can get tuning software for it.  Guessing by your description, you're not running throttle body.  That just means that the software costs a little more, but still there. You'd pay about the same for the software as you would for a good carb and intake.

Although I think it can be done with a Propane carb ( and thank you for the web site! I needed that!)  I caution against planning on buying a propane carb and hooking it to the engine and Hydroxy generator and expecting it to run like normal... !
Many things come into play with a Propane carb, the gas pressure for one as well as the Jetting
with Propane almost as much Air as gasoline is used when burning it in an engine, but with Hydroxy gas Much, much, less air is used... in fact so much less that I doubt you will get a engine to run with a propane carb and Hydroxy gas... it will lean the hydroxy gas out way too far to burn. that means extensive JETTING would have to be done to the carb... and the Jets on those diaphragms are NOT easy to modify.... I still have a propane jet off a diaphragm in my toolbox that I have yet to attack , its a cone shaped thing with a slot in it... the depth and width of the slot is the Idle setting and the CONE itself is the medium and full throttle settings and its only about 1/2" long and 3/8" in od. making it very hard to deal with!
after removing it from the diaphragm  I decided it was easier to make a new one on the lathe than modify the existing one !...
... I went to the Propane carb site and did see a high volume 2 bbl 1600cfm carb however
so 2 of those or even 1 on a smaller V8, might be the answer.
....
You simply cannot block off the outside air and run a propane carb because with the outside air cut off the vacuum diaphragm will not operate at all, there has to be a pressure differential for the diaphragm to operate and move the main jet... this poses a problem for the Hydroxy gas.... hydroxy gas don't need any ,or Much EXTRA air to mix with it...
with a Propane carb you have a bunch... How will you get around that problem ?
...
for Vaporizing Gasoline and expanding it 600 times you might be able to get away with it.... that is what I was trying to do... but for Hydroxy gas I think a simple valve is your best bet.... its inefficient, won't mix very good and down right CRUDE ...but has worked on engines so far... and unfortionately the ONLY method that I have seen that does!
.....
Granted some propane carbs don't have to have, a pressure diferiential to operate and those you could probly use fine... but the ones on that site were all vacume operated,or pressure operated... if you found a propane carb that had a Manual cam or ecentric that moved the main jet that would be the perfect canadate for the job... but I have not seen them for large engines AT ALL!
....
good luck !
...
Personally I think going to a regular carb fed engine is the way to go... Much easier to deal with I think... but I won't know for certain till I put one on the Old dodge truck! HEHEHE

I have had my map adjuster on now for 4 weeks. The first time I adjusted it I turned the vref voltage down to 4.5v. I ran it for 2 weeks and the milage went down 6-7mpg(wrong way huh). The second 2 weeks I adjusted the vref voltage up to 5.5v. I have run it for 2 weeks and the milage came back to base +3. I'm going to adjust it tomarrow up to 6v and see what it does.

Sounds like your testing it correctly to me...thats what I'ed do anyway...
I just have a problem when it comes to these enhansors/adjusters... some how I doubt they will take the fuel LEAN-NESS far enough, to show any real improvement in gasoline mileage.
I just think the computer in the car is smart enough to correct it if its too lean
thats why I think we need to go toward mechanical means of leaning out the engine...
ni-on-to-IMPOSSABLE in a electronic controled engine I understand , but I think its a must to see any real big improvements...
thats why I use the "Matt-Valve" as my Leaning-out adjuster... and it seams to work very well for me !...( I dunno if you can adapt the "Matt-Valve" Idea to your truck or not but where there is a will there is a way guys !)
....
even with my Hydroxy generator OFF  I am getting a consistant 30MPG out of my toyota truck now... I started with 22~24MPG as a base line...so getting 30MPG is darn good I think....
adding Hydroxy gas Now will only improve that further !
