Hey guys I've noticed that when I get on the Lightning sometimes (kick down from 4th to 2nd or 3rd) I look back and I see a cloud of smoke. Is this becasue I don't get on it enough? I remember awhile back I hit it hard and I happened to look back and there was a big cloud of dark smoke. A car behind me had to pull over. I did the same thing again right after that and there was nothing (no smoke) so I guess I cleaned it out? I really don't drive her as hard like I use to. I mainly putt around town 90% of the time. I know they run rich from the factory, so is this normal?
