I have a bullydog Triple Dog and a Diablo Puck installed on my 04. Prior to installing the Diablo Puck the truck smoked some, after install the Diablo there is no smoke but a noticable difference in power. What changes were made to cause this? I guess I expected more smoke and more power got the power and less smoke? I don't understand. I'm not looking for alot of smoke don't get me wrong but what changed?
