I havent bought it, but I thought I might. Here is what I found out, the Rear HP gains that they claim only come after, intake and exhaust changes as well.

This means that they claim an upgrade of 22 HP to the rear tires, but really you are only gaining something like 7, because the intake and exhaust will already give you something like 15 without the chip.

Whether or not loosing your car for three days and paying 300 dollars for it becomes the true question.

So far my impression of this is that unless you can change the overall horsepower of your car by 10% or more you can't really feel the difference.

I personally am not going to end up with a Jet Chip, but it might be worth it if you can get 22HP at the rear wheels.

In my opinion, you would be better off saving that money and putting that into a supercharger, at least they are available for your engine .
