I recently found out that my fast has had a turbo xs fuel cut defender by her previous owner. Since I bought the car used i have found out that it had after market exhaust and this thing now. I really dont know what it does or whys it even there i wonderin if anybody knew anything about this. Also will this blow my engine

What it does is hides increased boost from the ECU. With most modern fuel injected and turbocharged engines, if the boost would spike for whatever reason, the ECU would cut the fuel supply to reduce the load on the turbo. I don't know if the Volkswagen engine even does this since it has the DV to accomplish the same thing. Either way, if all the car has on it is that and an exhaust, it's definitely not necessary. This is the kind of thing you'd use along with a manual boost controller. I wouldn't want in on my car.
