SCG-1 users, what gain % are you running?
I'm at 72% DC now with a 10psi spring and goes as high as 13-14psi on street tires before it starts to spin and i gotta back out.
It will have more boost to push against the spring, taking less percentage total to make a bigger change
Mine has 6 settings, and the different between wastegate and 2 more psi is 40%
The difference between 16 psi and 18psi is only 7%
