C4 100+

The previous owner of my car took it to Callaway in Germany for recommissioning not realising that it was a 100+ car.
I think it runs great, but they recommended him taking it to a specialist in Switzerland to have a modern ECU and map. Has anyone done something similar, and if so was there a marked improvement?
