That could be ANYTHING... Find out what application it came from, and find the O.E. Specs on the turbo and what it is set...

Update on this.. I opened up the internal wastegate last night and come to find out its adjustable.. I turned down the boost on it to about 6 psi.. When I tested it, it was at about 13 psi.. for Airesearch

And most OEM actuators come staked from the factory so you can't adjust them.

One that you can adjust is the sign of a replacement turbo at some point... standard fair for an OEM turbo car.

I dont really understand what your saying here.. The one that I have doesnt have a rod on the outside of the turbo.. The wastegate valve connects to a diaphram with a bolt holding the diaphram against a spring.. If your turn the diaphram up or down it changes the resistance agains the spring.. Clockwise increases boost and counter lowers it..
