Just curious as to what the dealership does with the 2nd o2 sensor on the r-tune specs. relocate? if so, then do they weld the bung onto the nismo catback? or do they splice in a sim?
It was my understand that you could buy a s-tune or r-tune spec from the dealership. Not just take yours in and have them do it. In any case, no one out there has an r-tuned spec from the dealer? Just curious what they might have done to your car.
