Default 38mm wastegate spring test?

i was wondering if anyone knew for sure how to test teh psi in my tial gate. i kid i bought it from said it is a 9psi. basically what i did to test it was use compressed air w/ a boost gauge in line and blow air slowly into it. it starts to open at 9 and is fully open at 12 so is this a 9lbs spring?

No it's a 12 psi spring.

My WG spring test involves 3rd gear and burnouts.
