Pity Hartge don't make this clear on their own website, and to be honest, that's a lot of cash for a piggyback system........??
Am in two minds now
Edit:
I've just looked again at the German site, and now I know what I'm looking for, you can see the N55 kit is a piggyback unit, like the one they do for the diesel engines, whereas the N54 tune isn't and is a reprogrammed ECU unit, which is why I assumed the N55 was as well.
