Performance chips

From time to time I hear about "performance chips" that can be installed to optimize your engine's performance. Are they costly? Do they work?

Not too sure about this one but have you caught the Progressive commercial that takes about a chip to use to make sure you are driving great and then you get perks with their insurance? Seems a little privacy shady to me.

A friend of mine put one in his diesel truck a couple of years ago. He says it noticeably improved his gas mileage and that it didn't cost him an arm and a leg.
