I love the way you explain things. I had the same situation with a 3 port system. It would not make any more boost over 85 percent DC. However I never fitted a restrictor to the wastegate line I simply changed the spring in the wastegate which effectively lowered the duty cycle at the same boost and brought the duty cycle back where it needed to be. You make a very good example regarding frequency of boost solenoids. The Mac valve like turbosmart use likes not much frequency. In the range you mentioned up to 20 hz At 30 hz I found the sensor way to sensitive . This was on a 4 port system. Dropping the frequency to 20 changed the sensitivity a lot. In my case 2 percent would change things 1 psi. Reducing the value would make that around 10 percent is 2 psi. And I presume going further would change it more. I simply replaced the spring with a softer item and fixed it. Thanks for this explanation

Mark, understanding this theory through your video helped me finally understand PID to get my idle tuned. THANK YOU!

if you tuned based off waste gate psi,would it be the same psi in every rpm.
