I drive a diesel its an old smoky thing until it gets on boost but modern vnt turbos are fixing that issue as they boost sooner. rolling coal is a bit of fun but you just have to be careful who you do it to. I wouldnt do it to that girl but I do find it funny to watch. I have rolled massive coal through a real ritzy area in town where they all have there white fofo dogs out. Turned them into a 101 dalmatians. black spots all over them
