Doug - I have an electrolizer, a PCV enhancer and tinfoil on both oxygen sensors - but nothing more than that because I wanted to give the system a fair test.

But I do have to admit that today I was frustrated that my MPG this last tank wasn't quite what it was the first week - and since I finally quit racing it around (I was pretty excited about the performance improvement and went a little nuts for a few days....)  I was disappointed that it didn't come back to what it was the first week.  So, out of disappointment I added an additional 1/4 teaspoon baking soda when I refilled the container with the distilled water (which made a total of 3/4 teaspoon baking soda with 2 quarts of water) hoping that would improve things, and it broke the glass inside the canister - please note this is not a mason jar - mason jars can withstand a lot of heat - this is a canister type of thing that I bought from a guy at Ozzie's get-together.  I was able to find a replacement canister to get my system back up and running thank goodness - I would hate to lose it now!  I have a post in another area on this forum looking for advice with a picture of the system if you wanted to see it.  I think I might have a leak where one of the hoses connects to the cannister which I will address tomorrow, but waiting to hear from the experts if double the wire and double the water means half the baking soda or if the canister idea is simply a bad idea because the glass might not be tempered or something like that.......

My SO has a system installed on his SUV that is a coffee thermos thing - very compact and nice looking but he found it a little interesting to refill - he's worried that his mother might not have an easy time with that particular setup.  He is seeing 30% improvement with his vehicle and very excited about his performance too.  He had smog check and it had almost zero emissions (smog test guy would have failed the car though because he did not have a sticker from California Air Board clearing this system for use - next item on the agenda is how to address that).  His installer used the brake vacuum line, he said because it was the best vacuum on the vehicle.  His system also did not use a second hose to go into the air cleaner line like mine has. 

Do you have two hoses or just one?  Where did you have it hook into?  How much baking soda are you using?
