Ok, let me explain something here about my van. I find it funny when reading posts relating to my claim of mpg. Its not like im stating that i get some unreal number of 50 +, there will always be a hater in any given subject, maybe other owners are just upset for their vans get closer to the norm. Im not a rude person but when someone talks about a claim that i have, in my view they are dumb and should slap their mother. It seems too that many people are under the impression that these vans can not be tuned, which is complete BS. sure you wont gain 100 hp or whatever but 5 to 8 extra mpg can be gained if proper things are done which in my van a prior owner did whatever to gain such mpg.

 

"in my view they are dumb and should slap their mother." You sir are one... unfortunate soul in dire need of help.

 

a Chrysler speed density fuel system will simply put it back to what the original programing has it. Most if not all attempts to mod the van it be undone in most cases.

The pcm has the ability of adding and taking away up to plus 30% and - 30% of fuel and still run correctly according to the air fuel ratio 16.7 air to 1 part fuel. With out hard data to back up most of what U say it is most cases will not work.

I personally used a HHO on demand system and good descent results which I added hydrogen into the system. Only major issue was it was a vary picky system always wanted to be messed with and ket up like everyday sorta stuff.

 

Simply wrong but thanks for your comment

 

I get 6MPG in my 7000LB, V-10, 4WD Super Duty. Whatever you are getting is pretty good.
