Hello, everybody!
It prints very poorly at low and high speeds, although the flow is 200 percent what is wrong?
That is way too much.
A picture of a print would help quite a lot.
What slicer are you using?

You have quite high accelerations set for a bed slinger against 3hump_ei input shaper.
The latter speaks for rather noisy axes…
As the stepper drivers do not seem to run in UART mode you might adjust vref/current according to requested speeds and accelerations if everything is cooled properly.
But as @EddyMI3D already requested, we should clarify what poorly means…
If you still have the stock feeder the respective rotation_distance should be in the right range.
Maybe you just have a partially clogged hotend causing under-extrusion.
But who knows! 
Thanks, but I increased the flow rate and everything became awesome for me. I plan to increase the speed of the old man.
That is not the right way! You wrote that even with 200% flow it is still poor?!
Are you at 500% now?
And why are you seeking help then?
I didn’t know, but now I know the flow rate in the config is small
There is no flow rate being set in your config! This is subject to the slicer.
Maybe you just need to (re-)calibrate your feeder/extruder esteps.
Okay, I get it.
I recommend tuning the printer
