I fail to see exactly what you mean by this... I'm sorry.

I built one with all 2180's and I think it was pretty close with 120k
This was measured after the turbo was fitted , right?
Main PCB pin 1 voltage Turbo pin 1 voltage
+0.005V -0.002V
Main PCB pin 7 voltage Turbo pin 7 voltage
-0.053V +0.088V
Turbo pin 8 varies between approx. 0VDC and +2.5VDC as the threshold control is turned through its complete range of travel; Approx. +1.2VDC at the mid point.
From this, we can see that pin 1 should have basically no DC present (which makes sense), pin 7 can have some DC present, maybe in the region of ±100mV

my problem is that the turbo board compresses way too much.
it seems that the threshold range is not good. could this be a
broken 074?
Or do i have to adjust resistors cause its comming with 2180 instead of
2150. (already removed 47R and replaced 3k9 for 5k1)

No I don't it's 2181B for the audio vca/sidechain and 2180 for the turbo.
I changed only the 100K for 120K for ratio adjustment in the sidechain.
All other resistor changes are on the audio vca's.
It should have the exact same resistance values as the sidechian on your gssl. Any resistor value changes you made to your gssl sidechain should be done to the turbo as well.
Question: You are using the same vca in your gssl sidechain as in the turbo, right?
