The ECM reads the pressure difference between DPF inlet and outlet, then SCR pressure etc and someone is going to "fool" the computer with resistors?
In theory if you find resistors that matches the sensor feedback at optimum conditions, meaning no need for DEF or regen, then who knows, it could work...
Following that logic, in theory, you would need X value resistor for DPF inlet side, Y value for outlet side and then something for SCR.
In reality, after working 3 years with Cummins QSB and ISB engines and emission systems, I would not go fiddle any of those emission system and someone claiming they have fooled 2013 DEF system with capacitors is BS as it might run for minute or two, but lets see after 6 months....
