RaceChip for CDTI – Who has experience?

Hello together, since I intend to strengthen my Corsa 1,3 CDTI a little bit I’ve stumbled a little bit in the net. I came across the side of RaceChip.de. These power boxes, according to the provider, make a lot more steam under the (diesel) boiler… In addition, the desired power increase should also be adjustable, this would also be very interesting. If one of you has a box (RaceChip Pro) installed in his CDTI and can have his positive / negative experiences here on the Clüsseln? mfG Bernd
