Pretty sure if it's an 08 you would have top feed injectors. What are you trying to do? I thought TGV valves were a U.S. spec thing. Just looking for new injectors? If so, do you need to upsize them to support higher power?
@moshe_levy don't count on a noticeable hp gain from TGV deletes. In theory it can help, but will not do anything until you remove the more substantial bottlenecks in the system. If you want to make more power the stock turbo is the number one thing that holds you back. I did not touch the TGV deletes until I needed to upgrade the injectors, which coincided with moving up to a substantially larger turbo that required them. If you are considering a bigger turbo in the future you might upgrade the injectors & TGV deletes now, but you will require a tune immediately.
