Hello,
Is there any hardware difference between the 2 versions, or is it just mapping?

Thank you.

It's the same hardware as far as I know, different mapping.

However the 128ps versions are likely picked in the factory as the best preforming individual engines to ensure they withstand the extra power for the duration of the warranty.

might check size of the turbo fitted and fuel pump or injectors. if all have same part number then it must just be the map in ecu.
