I think the link in my signature will provide info on more popular modification pathways, and I think one could avoid talking in terms of pressure since it isn't very meaningful when the turbos are changed; instead one might look at mapping the car to work with a new turbo. The fuel rails and fuel pressure regulator your car uses can't really be doing all that much at this stage, and I don't think from the list of parts given the most has been made of the previous setup. Just my view. See the link, you'll find it interesting.

so your saying my current set up could do more?

Who's tuning the car? What are your compression/leakdown results?

I used to run 20psi in the midrange and around 12psi at redline on the stock TD04L-13T with stock injectors. Like said above,who tuned the car?
