Does this "Chip" work? Bosch 06a906032c

[BugCowboy]

I was wondering in this part is truly a plug in item, if it works and does it cause any harm?

Below is the add:
$65.00 total price
1998 to 2005 Turbo vw beetle performance chip adds 30hp to your car it has been gently used made by bosch part number 06a906032c easy to install all you do is plug it in

Heh, I saw that yesterday and the seller did not know what software was programed to it. The only thing that is for sure is that it is a factory ECU.

I talked to the guy and he said it plugged into a separate plug by the ECU. He took it off when he traded the NB in b/c they would not give him any $ for it. He also has a Nuespeed exhaust & air box for sale. everyone on the chat forum said stay away from this deal.

I would stay away from it myself. For this simple reason:
It 'gains performance' by lying to the existing system.

Why would you want to 'trick' your system by lying to it? Why not just program the system to work better? What happens if things DO go wrong and you over-boost? Your computer won't know you're overboosting; it'll just believe whatever you're telling it. Buncha lies & deceit & trickery.

Useless. The car's already got a very sophisticated, and very complicated system of sensors and readings and calculations. Just alter the requested/expected values and you'll keep all the benefits of the system in the first place.

30 hp gain sounds like wishful thinking

If it sounds to good to be true, It Is.
