Yes, I understand how the gain works. I started at 50 and have been working my way towards more stable boost, now I am at 75. The reaction time at 75 is still very good (suprisingly).
Without the restrictor, my issues were way worse.
The restrictor is between the turbo outlet and the BCS.
Plumbing is as short as it can be and I am pretty sure it is free of kinks (I should check that).
Like I said, I think I can get what I want but my setting and experiences seem to be a lot different than most (but similar to some)...
