i thought the C220 and C250 have identical OM651 twinturbo engines? also if it does have bigger injectors would it be possible to upgrade easily or is it a MB job to update the ECU with the new part?

I've just had my W204 C220 CDI remapped at Ecotune in Glasgow.
I prefer a remap of the ecu over a tuning box as the ecu can be tweaked to suit on a rolling road.
I know all rolling roads will give a slightly different readout but at least you can see the difference pre and post remap. Here's the graph from Tuesday

I think that injectors are the only difference.
In 250cdi the injector map there is values up to 120mg/stroke fueling level.
In all the other versions only 90mg/stroke.
90mg gives ~500nm, 120mg gives a ~ 600nm.
250cdi 4wd automatic
OM651 200cdi automatic

Maybe I do not understand you right, but there isn't anything particularly wise about this, it is only fun.
