On the Benz when I had it turbo'd (I know this is a Subaru thread), when cold Ohio winter came, I got about 3psi increase on turbo pressure.

I think a significant amount of the pressure increase can be attributed to air density, but I would imagine the boost might be creeping a bit as well. Internal wastegate turbos have a reputation for that type of thing. Either way, it's been fun so far.
