10 Cent Tuning: How Does It Work?

Hello,
How does tuning actually work?
- It's the case that, for example, at a signal box, there are 6 ohms present.
- The resistor is 300 ohms (with diodes).
-Electricity always seeks the path of least resistance for its flow, so with a 10-cent connection, nothing should really happen.
Can someone explain to me how the performance is generated?
I know that's how it works (the resistor simulates an engine control unit that injects more fuel and utilizes the excess air). I understand that much, but what about the resistors themselves?
Normally, the current should only flow through the signal box, where the resistance is only 6 ohms, right?
How does the performance increase? Even with the motor running, there are 6 ohms of resistance at the switchgear.
Does the resistance increase with increasing gas pressure?

Absolutely no idea.
Maybe someone can explain the history of resistance to me in detail sometime.

Hello,

The regulator operates on an inductive principle.
