The spring was in a small bag that came with the stage II setup. Nothing was on the spring to indicate the PSI that it represented. I just followed the instructions and replaced it. I believe if someone goes directly to a State II from stock - the correct spring may be pre-installed. On my setup and yours, the parts required slight modification (i.e. spring).
Disregard everything i wrote about the 7Psi label on the spring. I read something different and thought it was the Wastegate spring bag. You are correct in that the spring does not indicate the PSI it represents. Sorry for the misinformation and confusion.
