Is this preformance chip a scam or the real deal?

Thanks everyone! I will make sure not to look into it any further.

SCAM! As the price of fuel rises, you will see more of these scams.

This eBay seller has only been there a little over a month. Not long enough to get an accurate assessment of feedback. There is a person in the feedback section who was totally dissatisfied. Most of the other comments are only about how fast the seller shipped. Nothing about the quality of the product.

On a gasoline engine, no chip is going to make the improvements this company claims.

This so called chip sounds to me like a variation of the 100K resistor in the Intake Air Temperature (IAT) trick.

Look at the picture, only 2 leads. This is not a programmer that plugs into the computer diagnostic port. It is only a disguised resistor to replace a sensor

How this works, in theory, this device fools the engine management computer into thinking that the air entering the engine is about 32 degrees. The engine management computer adds more fuel to the fuel / air mixture and advances the ignition timing to compensate which is supposed to increase power. In reality, when the oxygen sensor in the exhaust manifold detects the rich fuel condition, it shortens the fuel injector pulses to correct the fuel / air mixture, canceling the effects of this device.

I have personally tried the Intake Air Temperature modification on several cars with mixed results. Sometimes it gives some improvements, but never more than 10%. Sometimes it does nothing at all. And frequently, it mess up the fuel air mixture to the point that the car belches black smoke from the exhaust and runs so poorly that the device must be removed.

Even when it works, the effects are less on a cool day. The cooler the outside air temperature, the less the effects are on the engine.

Did you ever hear the saying "A fool and his money are soon parted."

One way to judge if a product is good on EBay - look at the sellers feedback. here is what i saw on one of his feedbacks -"hooks into the mass air flow or the temperature controll. Not very happy."

basically he is changing the dynamics on the mass airflow sensor! thats all. i don't think this "chip" will work that well and if u really need performance then you have to put in headers and all sorts of things!

Sorry sweets, it is a rip off!
