Default Spring selection for Precision 46mm

Guys I have been puttsing around on a 3lb spring, I'm headed to dyno this Thursday. I have an Innovate SCG-1 controller. I want to make 10-12psi, but I don't want to hassle the tuner with a spring change on the dyno. I was thinking of combining the 'natural' and the 'green' springs, the chart says 10.5psi, and then using the boost controller above that. Does that sound reasonable?

Why when the solenoid can be used to raise past the mechanical spring pressure?

That sounds reasonable. 600/636 are some nice numbers! Is that from a 5.3?
