hi i have a imported legacy 2.0 twin turbo but the second stage of the turbo doesnt seem to be working prop my mecanic has had the car apart trying to sort it the vacum pipes seem fine turbos seem to be fine are there any valves or solenoaids that need to be checked to make sure they are working there are no mods on the car to my knowledge the second stage seems to kick in and then die off can anyone help as we are at a loss to know what to do now

You might want to try a Legacy only site, do a web search. I don't too many of us have even seen one of these in person let alone work on one. I did have one about two years ago, but I never worked on it.
