i think he wants boost lower than the stock wastegate regulated (8 psi), the boost solenoid brings it higher to like 12 i think. boost controllers only increase boost not decrease it. only way to decrease it would be to go external or get a new actuator with a lower spring rate. good luck on finding a new actuator with a lower boost rating than yours, but you can do what i did and take it apart and cut the spring, i got mine down to 5 psi like that. now i have a manual boost controller so i can set it from 5psi on up.
