Don't know how you conclude to underextrusion. It thinks the filament is smaller (2,89) than what it is (2,93) so more plastic arrives at the head (overextrusion).
I tried increasing the flow before, the head was already full and the feeder turned empty.
That's correct, if Cura thinks it's getting 2.89 mm, but in reality you have (measured) 2.93 (average), you should get more PLA mass per length /time, thus get over-extruding, in theory.
Unless, your measuring tool is not accurate....
Imho, the best way to find out if this is causing under-extruding is, lower your PLA ( ! ) filament diameter in Cura.
(I assume you've checked in Cura PLA, not ABS)
