I am testing a manual boost controller, Hallman PRO.
I am having trouble reaching my max boost 32 psi,

A guy from Hallman wrote:
The normal Pro will handle 40psi as well. This all comes down to the wastegate spring pressure. If the initial spring is too weak, the boost controller will not matter

So, do I need to readjust the actuator arm? I have new uprated t34 actuator and I did adjust the actuator arm be "half a hole" as recommended.
I can get 32 psi on the Amal, but we are testing this controller.
Thanks!

 

Looking at the Hallman website the device looks like it opens an outlet valve at a set PSI - like a bleed valve. Have you talked to Hallman about using it on the Cossie? Do they have advice on where and how to install it?

Well, Hallman say they have a boost controller for my Cossie that can handle 32 psi, I just have to get Extra heavy spring with it, and they can provide it.
I was just wandering if anyone here have tried this type? And if they did re adjust the rod from the actuator OR that should not be changed?

I did get only get 21 psi in the beginning of our test drive, then we replaced the nipple on the compressor (turbine) with a smaller one, then the boost went up to 25 psi. Then we did the same with the nipple on the controller itself and did get 32 psi, but the controller is turned all the way up.
But if Hallman say they can provide a stronger spring that can control 30+ psi, I definitively want to test that one.
I just wanted to be sure if adjustment on the rod from the actuator was needed, and ofcourse hear from anyone who has experience with the Hallman products.
