X axis ringing question

[TTVert]

This is on a maker select V2 running 50mm/sec. I noticed some extreme ringing so I went ahead and lowered X/Y Accel from 1000 to 800 and jerk from 20 to 8. While it did help I am still noticing some ringing. The bed is secured and not moving and the x axis belt seems tight but I don't know how tight it should be. I can pinch the two belt pieces and touch them but it isn't loose and I don't see any play per say. I still have the stock spring tensioner.

Here is the before/after changing accel and jerk.

Anyone have any insight?
