I also remember reading on Tial's site that the max boost is 2.5 times the spring rate not double. which would mean that 17.5 springs should give me max 43psi.
Im going to try the autronic solenoid which is exactly like the one Allen posted and exactly the type of solenoid TBC world electronic uses but charges 10x more.

A few simple options are.
- Use a stiffer wastegate spring
- Restrict the side port signal to the wastegate with a manual type of boost controller, and use your Autronic solenoid to control the pressure to the top port.
- Weld the wastegate shut.
I would start with the third option first.

Could not get enough boost today. Only 43psi!
Had an extra TiAL inner blue spring laying around. Cut it in half and placed it on top of the original blue spring. Now 52psi from 6500 to 9500rpm!All that with just a simple air compressor regulator valve from Home Depot!:

Profec B's are good to about 27-32psi. There are a couple of tricks to get higher boost but it also becomes very unstable. The Type S was a lot better but Greddy discontinued those!
Low boost on the fuel you're running!
