I just got my blitz dd bov welded on today and on the way back from the shop I wanted to try it out, but it sounded funny. It was like a slight toot noise rather than a woooshig noise. Does it take a little while to break in? Or do I have to adjust it? All the dirrections are in Japanese, I don't have a clue what they say. I am going to go wash the car now so I will keep trying it out. I'll write back soon if there is any diference.
