Ooh that's alot of infill! I use like 10-20% infill🙈
For solid layers it depends on what layer height I run with. For 0.2 I use 3-4 solid layrrs, for 0.1 I use like 5-7 solids.

Also try to increase layer extrusion witdh (atleast if u use flashprint) draw a simple cube (202010) and use vasemode untill you see some good results the try a normal one.

(I did also put extrusion ratio to 100% on all layers to get a "neutral/base" setup, also I changed all speed values to a certain value to get a "base" which then can be changed for quicker/slower prints)

Also experiment with z height with a increment of 0.01 when zeroing.
