I have been reading a lot of post lately from guys wanting to make more smoke. In most situations they are being recommended to get an Edge EZ or equivilant and/or injectors and that is supposed to work. When I first installed my EZ it would lay down some thick black smoke at low boost, but 3-4 days later the truck seems to be burning clean again. Does this sound normal? The box is still working, trust me. I can still feel the difference, just no smoke.
