serious smoke
I have a 2006 ram 5.9. I spend winters on the Texas coast(sea level) and the summers in Gunnison CO (7700 ft asl). All is good at sea level but at 7700 ft I get serious black smoke just driving around...

Not on a Cummins. Mine might make a little more if I stand on it but it's only a haze. In fact I don't think it would have any trouble passing a smog test even on level 3 (+100 HP).

I tried the Diablo Predator... that thing was redonkulous at making smoke!! Reason why I went to Smarty jr.
