VTG Map Tuning really necessary?

Postby Heiko » Fri Jul 06, 2018 11:06 pm


I started to remap a file for my newly purchased Mercedes C320 cdi S203 with an EDC16CP31 ECU.
To get a better fuel economy I raised up the boost map about 10-18% at the rpm range from 1200 to 2400.
As Im new into remapping I dont know if I should accordingly adjust the VTG map?
Is it necessary to make changes on the VTG in this case?

Thank you!
