This looks like snake oil..
 

Do they actually work ?

Ford Mustang 2005 Gas Fuel Saver Power Performance Chip - (eBay.ca item 120410461427 end time 29-Apr-09 21:49:35 EDT)

Hmmm.... my stang doesn't fit this module anyways.. anyone seen where I parked my LX Diesel???


Vehicle Application
Ford Mustang 2005 LX GT

NON-Diesel and NON-Turbo

Canadian / USA / UK & Foreign models

It is NOT for a diesel...

By saying NON-Diesel - they imply there is a Diesel out there..... All these types of systems don't work by the way. You need a programmer and change how the car performs to get fuel milage. Also how you drive and envronmental factors, Tire pressure, and so many other reasons.

..or they are bullet plating the script so they can change the name to a bunch of different cars and are too lazy to catch the ones like this on...like when was LX used for a mustang....it has to be pre 2005 ..and it just goes to show you who is doing the selling.

The reason I asked is that I have seen bunches of different adds touting the magical chip..in fact, I have heard end users spouting about their extra hp a chip gave them.

From what I am gathering for you, it that all these chip purveyors are selling snake oil and they have pulled the wool over many end users eyes..

Thanks, I will stay away..I don't need any more power (sorry snakebite :) ) but the gas milage interests me eventhough the 'stang gets much better milage than the trusty RAM.

I wouldn't ever buy one. I'll stick with my handheld tuner.

100HP!!! WOW. I'll buy one right away, what a deal...NOT.

Stay away from those, they're useless.

...so why do you need to buy a tuner..it is probably a one shot deal..should you be able to rent one or have someone at a garage do it for you ?? Seems awefukl expensive just to change an acceleration curve

It is a one time use, and it isn't. I agree it would be nice to rent one, but I like being able to use it myself whenever I please. I use it a few times a year to adjust my tire revs per mile because I switch between sizes frequently (my street slicks opposed to my summer tires). I also like being able to read any DTC codes that come up my self so I know what's going on. I did use it and will be using it again next month when I re-dyno my car to adjust the air/fuel and timing.

Also if you take your car in for warranty work etc (i cant with my intake) but most people can swap back to the stock intake and restore the tune to stock before bringing the car in. Also to make the swap for emissions tests.

If you get a fancy one you can use it for datalogging and or monitoring your air/fuel which can be handy especially if you have forced induction.

..Ford will not warranty you car woth a cold air intake ? ...they sell one them selves ? Yes, I see your point. I am a pretty easy driver but being a computer dweeb for over 20 years, I could see me playing with the thing an awful lot..probably best that I don't have one :)
