ET4 Pro - Calibration of filament transport

Hallo
Is it possible to make a recalibration of the filament transport on an ET4 Pro?
I have some problems to finish my 3D prints. The nozzle clogs after a few minutes of printing.
Before the nozzle clogs, you can hear a constant rattle on the stepper as the gear slips over the filament. This is a sign that too much filament is being fed.
I have also completely replaced the extruder, but that didn't help either.
I also measured the filament feed rate. At a feed rate of 100mm, 104mm is actually being fed.

Anyone able to help me?

In CURA set FLOW to a value lower than 100%, e.g. 93%. Check if you then get a better feed rate.
