Does anyone know how to change the upper limit of the VQ25DET boost limiter?

As far as I know, boost restrictions are already disabled in the Nismo (M5113) and Impul (AQ864) firmware.
VQ25DET. 2,5L. SH705507N. K-Line:

Thanks for the reply.
When I open the file in EcuBooster, I see this setting.

The maximum boost is limited by the capabilities of the boost sensor.

NISMO or IMPUL

If the performance of the boost sensor determines the value, it means that the value cannot be higher than 127.0.

This means that it is necessary to replace the boost sensor and enter new values ​​into these tables.

For example, this sensor

I see, so you are saying that changing the values is meaningless without replacing the sensor.

Yes, 127 is the maximum value for this table.

I see.
I understand well.
Thank you.
