What does the PPK sw flash cost to have done at the dealer? Anyone know off hand?
I just looked up the Giac sw upgrade. Looks impressive. There's no price listed however. Is this a load on to the the factory ecu or is it a piggyback system like the JB4? Like I said, my only concern is warranty repairs being covered. And I've not yet felt out my local BMW dealerships to see if they're at all "mod friendly".
