Sidewinder X1 quality issues after switching to 0.6 nozzle

[flat ferry]

I swapped my Sidewinder to a 0.6 nozzle. Ever since I've had the same issues on all of my Benchy attempts.
I've attached two pictures: the first is my 0.4 Benchy, which looks great.
The second is my 4th 0.6 Benchy.

Each attempt has been about the same. It has wobbly lines in the vertical portion of the door, and under-extrusion/latent extrusion just above the door frame, all in the same spot.

Hoping someone with Sidewinder/0.6 experience can point me in the right direction.
Thanks in advance, folks.

As for my settings...

190 nozzle, 60 bed
0.28 layer height, 0.66 line width
2mm retraction

have you done a flow test? and a retraction test?, I suspect there is not enough plastic in the nozzle from layer changes
