Is this real or a gimmick? Will it damage my injection pump?

I'm interested to hear from theorists but also someone who has used one.

Thanks!

I wouldn't personally, if it seems to good it usually is.
Here's a few things I found from google though.

Technically speaking, you don't have an injection pump on your 2004, the fuel injectors themselves are the "pumps." However, it looks like that device will work on oyur car. Its claims seem too high, especially fuel economy greater by 10%. If the manufacturer could do increase fuel economy by 10% just through some tuning, they would have.

Technically, it's also not a chip, chip generally refers to a tuning map change in the car's computer. These are better but more expensive. The box shown is called a tuning box and just fools sensors into giving more fuel. They also work and are removable.
