Vehicle 2014 VW Polo 6R 1.6TDI CR

I have changed original Turbo KKK BV39 to Garrett GTC1549VZ Turbo and Vacuum actuator from gtc1238vz

I searched on forums and found out that
The actuator in garrett works other way then KKK.
To be specific actuator return signal is opposite.

The only error that im getting is

P256300 Turbocharger boost control position sensor circuit; range/performance

can someone fix this
pm me for the map file. Thanks
