Question
Why truck smokes black and stutters [lack of power]

Answer
Hi Chaitram,
Black smoke is an indication of lack of air. Check your air filter(s), how much boost are you getting out of it? check if your air to air (intercooler) is plugged. check for torn intake hoses and ducting after the turbo.

good luck,

Matt
