Not at all one pays to be a ecutec dealer the other has been refused a dealership and has found a back door .
One has more experience and I'd put money on a better drive .
It's your car , but for the price of a tank of fuel if I was in your shoes I know where I'd be going for mapping and on ethical grounds .
It's a bit like you getting a non gas safe registered person to install a gas appliance !
