Hello everyone,
It is a Golf 2.0TFSI with DSG
Shortly specs; GTX30 turbo,External wastegate,RS4 injectors,Autotech HFPF,dual LPFP (Oem and aem),Boost controller etc..
No way overboost or dtc.AFR good,long and short fuel trims are good,injection timing max 5.87ms,any not knock but still throttle is closing till %50
any Torque intervention doesn't appear by DSG in vcds block 122.
What can cause throttle to close?

Logs are attached


Any help is much appreciated

i think maf scaling done right,no knocking, LTFT is well enough.Nothing changed when I unplugged of maf sensor.

I tried a Mafless file but still throttle closes
