I need to replace the original 2.5bar MAP sensor with a 3bar one from tdi engines.
I have a 307 1.6hdi with hybrid turbo and 1.6bar of boost.
New sensor is 0281002401 or VW 038906051C
I have seen the 2X1map used in VW dumps, but my dump has a 4x1map for the same function and I'm not sure my linearization is correct. With engine off it measures the same pressure as the atmospheric sensor, but the car seems to have some boost issues.
Here are my scalings:

382641382642

Can you please tell me what you think about that?

You may try just changing both 2500 to 3000.

Without axis rescaling?
At first I did just that, but I got a DTC about value implausibility.
Now everithing seems OK apart from some minor boost problem. Boost is slightly lower than requested and I wanted to be sure that rescaling is correct before investigating further.
