Default GT5 in TDR questions

Greets! I switched out my black full sizeVBar in my TDR for a GT5 a little while ago and I am really loving it.
I do have a couple of questions and wonder if anyone is in the know?
I just unplugged my servos and rx (SBus) during install and the center on all my cyclic servos seemed on par,as do the end points. I took for granted that the tail servo worked the same but when setting endpoints for the tail servo I got quite a big difference! I am around 120 in one direction but over 200 in the other. Piro consistency is good but I wonder if anyone else got similar results or did you reset the servo horn?
Also, I have a slight bounce on piro stops that I can't get rid of. My P gain on tali is 75 and I gain 65. Any higher and the tail starts oscillating during sideways loops etc. I have tried different D-sense values from 5-50 but cant get rid of it. I am at 5 now as the bounce is the smallest at this value. I am using BLS451/251 servos. Tried a bit of smooth stop today too but it did not help.
Any suggestions to help get rid of the bounce?

Adjust your pushrod until you got similar "bounce" on both CW and CCW, the adjust D value.

When i used G-T5 in my TDR travels to both sides was equal (tail slider in middle as is described in TDR manual). I got best result with this tail settings:
P 99
I 90
D-Sense 0 (any other value than 0 caused bounce on stops and wag with much lower P and I values)
Tail stick dynamic 30
DMA cyclic 5
DMA pitch 65
Tail-D-DB 5
Tail symmetric 0
Smooth stop 0
