05 with 120k on it bulletproofed but has recently started smoking all the time. I have no power loss but the truck wants to hop forward at lights. Turbo, Injectors or the ficm? Thanks in advance

Is it surging? Ive heard of several instances where it was fixed by performing the VGT relearn strategy and clearing the KAM. Also could be the ICP sensor, try unplugging it and seeing if it continues (it will set a CEL).

Check your EGR valve too, might be sticking.
