im selling my turbonetics wastegate and the buyer wants to know what spring comes in it.

The boost signal from the compressor outlet (fitting on the turbo) goes to the lower port of the wastegate. The lower port is the one furthest away from the Red Turbonetics logo that is on the polished diaphram housing (top). The purpose of this signal is to open the wastegate when the spring pressure is overcome by the pressurized air. For this turbo kit the spring in the wastegate is a 9 PSI spring. The compressor will produce 9 PSI of pressure at the outlet but after the pressure drop across the intercooler and charge piping the pressure at the intake manifold is actually 8-8.5 PSI.
The boost signal line from plenum (intake manifold) goes to the upper port on the BOV. That is the port the is closest to the red logo at the top. The purpose of this line is to hold the BOV closed under boost. When you close the throttle plate the immediate vaccum condition in the plenum caused by the closed throttle pulls the BOV open until the spring overcomes the vacuum and shuts the valve again.
Hope that was clear enough...

it is a special wastegate spring.
It is rated at giving you 8-9 pis, but it has been known to offer a special scramble boost setting.......
Just kidding, don't flame me too hard.

I do remember the box that the wastegate came with said 10 psi on the side of it.....I typically saw 8.5-9.5 psi on my turbonetics kit........
I used the overboost correction kit, and never really had a problem.....I think I logged a low 10 psi value once or twice.

Explain to me how that would be possible considering the highest rated spring available for the Evolution wastegate is a 9 PSI spring...

i can't explain it........i didn't print the label on the box.
no, I sure don't. My wife tries to throw away everything asap. 
I am only recalling it from memory as it struck me as odd......
whatever the case may be, I never had an overboosting issue.
