As some of you know i recently made a new video on youtube. YouTube - A LITTLE BLACK SMOKE... CUMMINS POWER!!! Most of you suspected i have stock injectors, but i had a buddy of mine who is a diesel fanatic come over last night and he suspects that there NOT stock because at idle my fuel pressure sits around 25... He thought it was just the ty power puck why i couldnt blow great black smoke... what do yall think? could my injectors be dirty?
