one possibility:

'Modifying the signal from the rail pressure sensor.'
'resistor in series with the signal line from the sensor, all connected via...'
kick-down switch on the accelerator pedal (when full throttle is engaged) and an additional switch in parallel.
to disable the entire thing.
In addition, I would suggest adding a second resistor with three diodes in series, connected in parallel with the other resistor, to reduce the distortion in the area of maximum pressure.

This method is the same as the one used for the vacuum pressure (boost pressure) sensor.

- The entire system provides approximately 15-25% more power and torque.
- The degree of distortion increases with increasing rail pressure.
- In idle (when the kickdown switch is open, i.e., full throttle), with a sensor voltage of 1-1.3V.
approximately 3-6% more pressure.
- In the partial load range (when the switch is open), approximately 6-13% more pressure.
- In the full load range, up to approximately 1000 bar, there is about 13-18% more pressure.
- In the range of 1300 bar (maximum pressure), approximately 13-16%.

Warning!!! Must be adjusted using a diagnostic device.
- The duty cycle of the pressure regulator must never exceed 80%.
