I would run a 10psi spring... if you're gonna run a minimum of 10psi then why waste time with anything lower.

Sure, your boost controller is what regulates how much pressure you run, the waste gate spring is basically for a "minumum" amount.

I have a 10psi spring and I've ran well over 20psi on it.
