Some infill not reaching walls ?

Update:
Last we heard was: My final thought - it's a hardware issue, super long bowden tube, very high extrusion rate.
Today I can confirm that once the extruder was replaced with a BMG clone, all the issues went away!
I had seen filaments silently (no clicking) slipping but I had no idea of the extent of the problem. It wasn't just an occasional slip here or there but systematic and consistent slipping, mostly at the point when a new line is started and the filament is sharply accelerated.
Happy Happy !!!!! ......
Oh, I should mention that the slipping happened at well below the theoretical extrusion capacity of the hot end .... don't know at what point things start slipping but i'd take a guess at 30 or so percent of the the theoretical extrusion capacity.

I replaced my second extruder today.
My pressure advance figures went all over the place in the past - even with the same material and same conditions. PA settings are now identical on both extruders even though one is running PLA and another is PETG.
The cause for all the problems, as mentioned before, silent slipping of the filament.
I am absolutely amazed at how much time I spent trying to figure out various issues I had with this printer when all it needed was a properly working extruder!
