Hey im from Australia and I have been watching a lot of usa trucks and wish I could have one but instead I got a lil 3.2 lt none turbo nissan navara I'm just wondering how the hell do you get your diesels to put out so much black smoke is crazy is like a factory

 

Well it's as simple as the more fuel you get into the cylinder the black smoke you get. It's really just fuel that never burned properly . The size of injectors or just a simple program on a chip.
