Installed Forge replica bypass vale = lower boost!?

[M_GORDON]

Hi friends!
I´ve a 007 and the last week I change the blue spring for the red spring.
My car is a ABY with a lot pieces and remap of an ADU. Before, the pressure was 1,7 and now only on high gears (5 and 6) and sometimes go to the 1,7bar.
Normally go to only 1,5bar, why?

But i now i've got the good sound when u go of the throttle, not the ricerocket pppsssssssjjjjjj but the one one thats sounds like friggin bird but that tells me that the spring might be a bit stiff for the car cause isnt that the sound when the bypass doesn't open and the air goes back to the turbo? or am i wrong?

Somehow it seems to me that you cant tell the difference between turbo stalling noise and bypass noise. When you look at old S1 videos, you can hear how air goes back to compressor blades. My brother had this issue when installed an T04E to his S2 3B, but that noise disappeared after installing two stock bypasses.

Btw, I'm using Dahlbäck big bypass valve and it makes a lot of sound.
