I just had new injectors new head gaskets and heads reworked and now it don't blow black smoke like it used too. What gives I'm still running programmer and it doesn't feel quit as strong as it used to be. Do the heads have to get broken in for me to get back the power and smoke I've came to love out of my duramax?

your probably running more efficiently, so u will smoke less. good injectors will allow u to maintain high pressure, your fuel will atomize better and burn faster. increasing power and minimizing smoke

 

K thanks I understand less black smoke is more power but I do kinda like seeing a black cloud from time to time
