so if you have an idea please tell!

 

Sounds like you developed a boost leak. Is the sound that your hearing a "hissing sound"? I would check and recheck each coupler and/or hose from the "y-pipe" to the IC and then out to the Throttle body.

Those clamps and or couplers can come loose. You might have split a hose or coupler. These splits are tough to see while on the car. They sometimes split where you can see them and only "show" the tear under pressure. When I had this problem, I just removed checked and reinstalled each part to make sure that I didn't miss anything.

 

Check the crossover pipe.


Mine was overtightened on the turbo side and popped out of the coupling.
