mine has started doing the same it idles perfect at around 7000 psi if i grandpa the throttle it runs fine but if i get on it my rail drops to around 5000 psi and starts a steady stream of light black smoke and acts like it dont wanna go i think it might be my fuel filter but i dont understand the black smoke i put my bdtd to true stock and it still does it
