N54 Boost oscillations N54

[TiAgAu]

Probably basic tuning for most on here, but i'm new to bmw tuning.

I'm looking to smooth the boost out as you can see in this log i'm getting abit of oscillations from 3200 to 4200rpm. why does PID drop WG when i'm not at target boost? oscillates up and down below target? Do i need to reduce the WGDC D-factor more?

TIA

Lower D-factor multiplier a bit. Raise base up to match closer to after PID. Should clean things up.
