Hey guys. I have a 06 sti and there's a lot of aftermarket parts on it. Some things were done by the previous owner and I am not sure if there is a tune on it now or not. I just got a COBB acess port and I don't want to mess up a existing tune by using it, but again not even sure if there is a tune or not. What should I do???
