Yes it did stop the smoking. I put it in and then left it till the next day. I cold started the next day while looking back out side. It just puffed very little when i did start it. The next day after, nothing. Just clean exhaust. I definately have increased power and MPG. Before i was just almost getting knocked in the seat when accelerating hard. Now, my CVPI is now how it supposed to be. Balls.
