You can adjust your wastegate opening by using a manual boost controller so you can set it to open a 20 psi if that is what you want to run. Travis

What are the t-25 internal wastegates set at?

 

[Batman™]

10 or so. the stocks turbo usually makes around 10 psi, can be a little more or a little less.

I have the same turbo and it fully opens at about 4700 rpms and it puts out 11 pounds with out using the boost controller.

If you aren't hitting full boost til 4700rpm then you have some issue's you need to address.
