I have something against buying parts off the shelf... So I came up with my own boost controller.
What's wrong with the normal boost elbow? It does work to increase the boost pressure, but It makes the wastegate opening curve even worse then it is stock. With my stock 96, it makes about 22 psi with the stock wastegate and no boost elbow. After some testing, I've found it to start opening around 10 psi. So when we're at any boost pressure above 10 psi, the wastegate is already starting to open and bleeding drive pressure away from the turbine. With this setup, you also have what's called 'Boost Creep' where the boost climbs as the RPM's go up. This is because at 22psi, the wastegate isn't even half way open yet. The boost elbow does not fix these problems, and neither does the ball and spring type boost controller.
After lots of complex designs involving a 3 way valve, I opted for a more simple approach.
I bought a $23 eBay fuel pressure regulator and modified it, which included replacing the diaphragm with a piece of tire tube (temporary), and changing the seat a bit.
Using an air compressor to mimic boost pressure. The wastegate is fully closed with no pressure in it at 28 psi, and fully open at 32psi. This means that the wastegate will do everything it can to keep us at/near our 30 psi setting. This also means we can enlarge the wastegate port, without fear of it making the wastegate open prematurely. Success!
