Little puff of black smoke?
Hey guys, I was wondering if this is normal or not. My truck has the SCT tuner on it with NO power gains just an intake, DPF/CAT delete and EGR shut off. I started to notice when I get on it the truck shots a small light haze of black smoke. Is that normal even though there no power gains? If I roll into the throttle it's fine just when I get on it the truck does it. It's 85 degrees where am at I have the A/C on most the time runs and drives fine fuel mileage seems to be the same. Just wanted to get your guys view on it. Thanks!
