I believe I determined I have a 7.2psi spring in the wastegate. I had the spring out twice and I'm fairly certain it was green. HERE is the guide from Tial. I would have sworn the boost gauge didn't go above 6 though, but I guess I was trying to watch a lot of things a the same time.
I'm not sure if I'll go with the 8.7psi or the 10.1psi spring. Probably the 10.1psi...
EDIT: I believe the difference in boost readout is because I have my boost gauge referenced off the manifold and the wastegate gets its pressure off the compressor housing.

Sorry no decent under-car photos. I tried to take some tonight and it just didn't work out. Next time I'm under the car in the daylight I'll take some.

Overall I have to say I'm extremely happy with how smoothly the build went. I am also a firm believer in v-band clamps now!
I've only had it out for one drive to help dial in the tune, so I can't really comment yet on how fast the turbo spools etc. I should have more input after this weekend, and my also post data log info.
