I don't know if it's been adjusted in rom raider or not. My cobb unit i have been told no.
Trying to adjust my outback so it will read correctly with 255/40R17's. I currently run 255/50R17's but i now have a 6spd so i can decrease the size.
I read about a piggyback device that adjusts it but haven't fund one compatible with our cars.
I searched and found nothing on the subject.
Thanks for the help
