I highly doubt it. I wouldn't mess with your vehicles computer unless you know what you're doing. I did a little reading up on it and it uses a lot mumbojumbo that sounds good to trick you into buying it. It changes the mixture that your vehicle was SET to run from the factory. This product claims the vehicle could be set to run too much or too little fuel. Since you can put it on any vehicle, how does it really know the demand your vehicle needs?





I'd say stick with the old fashion fuel savers like replacing your air filter every other oil change, rotate your tires every 6,000 miles, keep your air pressure at the correct psi, change the fuel filter every 25,000 miles and a fuel system cleaning.

Says you get a box programmed specifically for your vehicle if you read, And it plugs in with little work. I am a mechanic also. It could very well work. Report Abuse

I've personally never used it (nor would I). I would think it wouldn't work the way they claim it does. A good tune-up would be your best bet. Change the plugs, air and fuel filters can save you a lot in gas and make your car run better.


From the ad I saw, they say that they can get 40 MPG and 130 extra horses out of a Ford Crown Victoria. That would make the car run with Mustang GTs and get great gas mileage at the same time. Sound too good to be true? Well, that your first red flag. If it was that easy (another $28) don't you think that every manufacturer would have this on their car from the factory and then advertize these great numbers. They would sell thousands more cars.


I'm sure there's some 'tweaking' every car has for better air / fuel mixture. But I would seriously doubt this can live up to the claims it makes. And additionally, if you put this on a car that is still under a warranty, you have now made the warranty void.


My best advise without ever using it is to stay away. No one can make a Crown Victoria get 40 MPG and have 365 hp at the same time or Ford would be doing it.
99 % of the produces are useless. fitch fuel filter is one of the few gas savers that work.

All of these gadgets are junk and don't do anything. If they really worked they would come on the cars from the factory.
