self-tune: initial concave/step boost target issue

[YangLIU]

hi fellows,
I have an 09 e90 n54 335 (IJE0S). I just start learning self-tune for my car.
i have a question about the boost target. i attached 3 logs of my self-tune logs, i can see the initial boost target has a deep concave/step. i tried to set high load request all cross the rpm with modified BLM/LLF as below attached screenshot, but unfortunately it didn't help. i checked WedgePerformance tune's log, they all have very smooth/sharp boost target at the beginning. May i know the reason for this?
thanks in advance!
