V-Core 4 - 300 - Gap between upper and lower
Another good indicator in your relative belt tension is:
you do not have any noise in them.
So it seems that your gantry is well built and your screws are tight.

Y could be at 5500
X could be at 16000
These are my values. I assume your belts are either too tight or too loose.
I assume too loose. I got the Same values with too loose belts.
Used prusas belt tuning app and a reference too frequencies in this discord to tune the belts.
BUT: your Graph will be changing when installing the hybrid belt.
What is really good at your graph is relative belt tension.
I would leave it as is and proceed with hybrid.
You’ll get more chances to tune the belts when rebuilding your machine or modding it.

Make a shaper graph for both axis and post the result here.

Your relative tension is fine. The peaks align on the same frequency.
Usually that also indicates that your belts are of the same length.

I think there is no tension you can aim for. Especially not when reading these graphs.
The graphs can not show you absolute tension, only relative tension.
At least that’s what iam reading here and there

vibrations increase when right hybrid tighten
I think it’s because of resonance frequency.
If you tighten a belt, the resonance frequency gets higher.
If that frequency matches that of your printers movements, you’ll get an increased peak
