No, it's not... You are trying to cheat yourself. Doing it is the same as remaking 2,5 meter measure to 3,0 meters. 2,5 will never be equal 3,0. Think about it.

With this scaling car will lose power for sure...

You still don't understand... You want 2,5 bar sensor to show 3,0 bar. Change sensor to proper one and adjust voltage and pressure. You have right address.
Or maybe you want me to buy 3,0 bar sensor, came to you and change it?

Everything is written. Read and think twice.

I am change sensor in car already to sensor of 3.0 bar. But i need in flash to change scaling to 3.0 bar. Adjust voltage and pressure? I do not know how to do this in file. That is reason what i am ask here on forum that someone do it for me. I am not tuner !!
Thank you

You mod is ok if voltaje/mbar is equal to ori sensor, if not then wrong. What 3bar sensor did you install? Check that info from 3bar sensor spec or other car flash with that sensor.
