How does this little gadget work? Can you switch it back to stock?

I think that the part you posted a link to allows you to hook up your tuner to your pc, I believe you would still need to buy the actual tuner.

Oh i thought it was just some chip that did something with the fuel, like those scams on Ebay lol.

Yeah ty is right you still have to buy the tuner, you can switch back to stock whenever you need or want to. I just bought a Diablo Predator tuner for my 2008 F150, and Im impressed with it. The only thing that I wasnt impressed with is the lack of customer service on Diablo's side. If you need help and call them expect to be on hold for at least 30-45 minutes. If i had to do it over again I would have bought the Xcal3.
