One thing to add here. Trucks startup with different main and pilot timing maps, different pilot duration maps, and different rail pressure maps when the coolant is cold enough. All these things can add to smoke upon startup with a deleted truck. I modify a lot of this with Warp but I do leave the cold coolant temp rail pressure mapping alone. If you try to run normal temp rail pressure mapping when the engine is cold, she will rattle hard when you accelerate. I've done it myself, doesn't hurt a thing, but would freak most guys out.
