Good evening gentlemen. This is my first post here, don't give me too much slack I've got a question about my lml. I recently installed a flo pro exhaust and tune. Since these mods I get a puff of white smoke in neutral and park if the engine is revved...I don't mean bouncing off the limiter, but up to about 1500 rpm. The smoke only appears after the throttle is let off, it's white, smells like diesel, is not thick and does not continuously come out. Just a quick puff like you'd get black smoke if you romped on it going down the street. Does anyone have any similar occurances? Maybe a fix? It's a 2015 so I'm hoping it isn't the injectors already. I have only tried injector cleaner this far since I'm new to the diesel world and don't want to hurt anything else. Any help would be greatly appreciated. Thanks in advance guys!
