2013 F150 Supercrew Platinum Ecoboost w/ 900miles. I get a puff of black smoke out of tailpipe when I accelerate or step on it for a down shift. Normal?? similiar to the "puff" from my '99 F250 7.3L Powerstroke. also....anyone feel the rear of truck "shimmy" at LOW speed? Less than 15mph. feels like someone is pushing back n forth on box.(side to side)

Turbo engines do tend to be a lil sooty from the exhaust. They run a lil rich. Shouldn't be of any concern unless it's too excessive and if any noticeable performance issues arise
