Has anyone tried the Fitch Fuel System Catalyst.com I saw it on "Horsepower" on TV. They tried it on a dyno and it seemed to work.
But they were seeing the difference in octane at 6500 rpm. Summit sells the set up but did not go into the gains in fuel mileage or if you could use one grade lower in octane.
In my opinion, I think that if there was a specific gain, the auto manufacturers would use it to increase mileage etc. in thier fleet.
But would like to hear from someone who has used it.

i second that request for someones experience with this product. i was looking at it for myself....

During times of high fuel prices these types of devices always gain in popularity, but the over arching fact remains if they are really that good why do the auto manufacture not have them on all their cars? There is absolutely no reason for the manufacture to reject a device that would help them get better milage.

The attached web site has a number of reviews for your reading pleasure. The last post on the site is probably the most informative and subjective review.

Unfortunately the magic bullet has not yet been invented. I will tell you that I did gain about 2 MPG installing the fuel injection on my El Camino, unfortunately I gave it all back using by regular application of the fun factor. Harald K
