I have done this mod buying my bike.
It was delivered at 100 hp and tuned up to 152 hp at the first service.
It is indeed only a sofdtware modification: the mapping of the engine is changed, and it does take 1 memory location (out of the possible 13 available, if I'm correct), so I am now at #2.
If I upgrade to v7 I will be at #3 (which doesn't bother me BTW).
There is no hassle whatsoever with the modification.
Andre, I reckon you live in Belgium, since this country is typically taxing vehicles based on hp.
