white /black smoke....0087code
 

Putting out alot of smoke at heavy throttle. 0087 code frequently....worse when towing Rebuilt long block 70k ago, New cp3 last week, Injectors within parameters, ppe economy tuner 4" turbo back straight piped ..built tranny s&b intake, pcv reroute. What could be causing this after all the parts thrown at it?

id say get rid of the ppe tuner for now and see if that helps...scott:humm:

Tried restoring back to stock but no difference..possibly vane position sensor /turbo weak ...don't know what to start with at this point. ��

well when was the last time u changed the fuel filter...scott:humm:
