Default vortex valve mpg

Okay,

after a second fillup, in stop and go driving I am still seeing a 2 mpg improvement. I wish it was more, but I will take it just the same.

I have been trying to drive the same way I did with the tank before I installed the thing, for what its worth.

I don't consider the ten percent improvement adequate, and a far cry from what is advertised. But, for thirty bucks, who can complain?

I wonder if it would help to reset the ECU?

You might be right, a battery disconnect could be in order. It couldn't hurt.

I read something a while back about these additions (Vortex, Tornado and other brands) and it may be worth mentioning. I admit upfront I have absolutely no experience with them. It was an independent study that found no noticable difference in economy. My understanding is that the swirling airflow that is created is negated when it hits the air filter. Further, if it placed after the airfilter you have the risk of one of the fins breaking and going directly into your fuel injection system and really messing things up. This is what I read. Take with it and do what you want.

Another interesting point though...... on my 1980 Kabota diesel tractor....... the air filter is designed with the fins to create the swirling motion as it heads to the carburetor. A factory design, but this is after the air has passed through the filter.

My two cents........ and worth every penny of it.

Nice find. Even if it is installed after the air filter, swirling airflow will hit the
TMIC core so I also agree that the feeling that it works is similar to "placebo effect"

I have an NA Baja, so that may not be an issue.

It is not surprise that the "placebo" effect is noticable when you step on the gas, since that is when the butterfly is open and out of the way.

I don't consider my improvement in mileage a "placebo" however. What will tell the tale is a nice highway trip. Up to now I have always gotten 26 on the highway, so it will be easier to see a difference, if there is one.

Interesting about the Kubota tractor. Interesting about "hemi" engines too. ;-)

My bad, i didn't notice that you have an '03. Sorry, then It really might work for you as long as it is installed after the filter! Just make sure that it is installed properly and do routine inspection.
Kool, keep us informed on the mileage.

How the heck did you get 28 mpg with a turbo?? Best I have done so far is 19.9 mpg.

Normal driving(this is hardly) I get about 20 - 21MPG which is not bad
When ricers, SUV's, and V8 trucks mess with me, I get about ~16MPG but who cares as long as I smoke 'em.

I have NEVER gotten 28 mpg, and I don't even drive a turbo! Thats amazing!

(Of course, now that I have a Vortex valve I plan on getting over 35 mpg on the highway, so it all evens out!) ;-)
