Like what was stated above, add more wastegate spring. 15ish is about all that you can milk out of an 8 pound spring. A manual boost controller can generally "double" the spring's opening pressure, so 15 psi is about par for the course.

Switch boost controllers and wastegate springs. That simple.
A proper boost manual boost controller will be able to restrict flow down enough to keep any manifold pressure from going to the wastegate.
But if you have a weak *** spring and lots of exhaust backpressure, the exhaust will push the gate open.
