Boost presure leak

Boost presure leak
Hello,
In first time, i'm sorry because i'm french and as you know frenchies don't speak english very well so if you don't understand it's normal.
I have a 996 TT and before the boost presure was always at 1.1b.
Sinc few month, i only have 0.9b.
I have changed the DV and the N75 solenoid and all the boost hoses are OK.
In france, all the professionals don't find something but i'm not sure thuy know what tey have to search.
I have made a tool to test the boost leaks. It's a plate i place in place of the airbox. But when i try to test , i have lot of presure which go out by the oil filling stopper. I don't know where the air can pass in the oil system.
I have also durametric and i can see the value of the maf is at the maximun at 5400tr/min and after he don't evolve.
I can say if you have understand all i wrote but if someone can help, it will be very nice.
In France, lot of people read this forum because we can find lot of nice things
best regards

Another question. to increase presure, we have to change the value in electronic or only modify the WG. I ask that because if there's a boost presure leak, that could be the fault of a spring defect of the WG??

I have asked this question because I thought that the WG fixe the pressure and the DV stop the excess of pressure in the holes when you stop to accelerate. But it's not exact.
If we have a problem with the DV, the pressure regulation could be bad, that function like that???

Hello,
I have made a tool to find my boost leak from the TB and I think I have found it
The air goes out by the little hose which is connected here
I think it's this one and the two valves must be bad
Am I right??? And what is the role of tis hose???
