Everyone has heard the old saying, If it sounds to good to be true it's mostly likely not. I was looking at 2 websites offering Performance chips and was thinking this may a case of to good to be true.
Here's what these site claim:

the first 3 really seem impressive. I don't think a cat-back exhaust system would give that much HP gain with a 8mpg gain. The price is only $60-$70. And let's not forget the anyone can install it in 15 minutes claim. So? To good to be true or does anyone have experience with these chips?
