What!!!
The car need a dump valve, blow of or what you like to name it otherwise you will kill the turbo.
And it should always on FRS be a recirculated otherwise you will run in to trouble, so that was already checked long time ago before I ran in to this problem.
My answer to my thred was if someone ran in to a simmilar problem this might be a solution.
