^^ What he said, or unless you want a higher boost level than what is available (the highest I can go without a boost controller is 17psi.)
Also note that the boost level they claim may not be what you actually get, it takes a little trial and error sometimes, with different spring/port combinations. I think they have a disclaimer stating this as well.
