It's only if you change the PCB and soldering path to the shunt resistors.
The fuse resistance does not affect the calibration. You have pics of your mod?

The only thing it can affect is the burden voltage.

Have you seen where the sense wires for the current shunt are connected? (This can affect the 10A range, but not the uA range)

Burden doesn't come only from the shunt, it's the entire path through the meter from input to output.

It has nothing with burden voltage to do, but where you connect a updated fuse to the circuit board.
