Hi All

Been playing my K04 PID pilot map (KFLDTV) to improve driveabiltiy and trying to understand why at low boost at part throttle the AFR oscillates.  Starting to wonder if this is a sign of bad waste gate.  This is for a 1.8t AEB with M5.92 so logging data is not great but I do have matched logs and AFR for when it happens.

Much appreciated if anyone can offer advice for how to get rid of this.  Boost seems fine at the higher loads and meets desired loads.
