How can you tell the wastegate spring pressure?

I dunno if I posted this, but if I did, then I lost it, and have to post again.
Anyway...
I bought a tial 35mm wastegate via ebay.  From some seller who is the owner of tuneablecompacts, and doesn't list wastegates on his site??  
Anyway, I mentioned that I needed a .3bar spring at most.  I waited a week, didn't get it, waited another week and he said tial was finishing the wastegates, and they would drop ship the gate.  And 2 days later, the gate was at my door.
And on the box, there is no sticker from tuneablecompacts, just tial stickers all over.  
And a sticker with a serial number written by hand, and a line: "Spring: .45 bar" written in hand, in pen.  But then in a different pen, .45 was scribbled out, and a .30 was scribbled over it.  And even the packing invoice says "Wastegate 35mm .3bar (4.35 psi)" on it.  And the guy that I bought it from said it would have a .45 bar spring in it.
I just don't know who to believe.  And if it is .3 bar, why is it so hard to push.
I intend on installing my turbo in 2 weeks, and I just don't want a 6.5 psi spring on my stock fueled car and have to drive around at 2500 rpms for 2 weeks till another paycheck.
So... someone give me some advice.
