I just drove to Aurora Colorado today from Ohio, and noticed that my truck is smoking a lot more than before. I have a hypertech on my truck and it smokes like my sct did before. I am wondering if it was the almost straight 1200 miles of driving or is it the altitude that is making the truck smoke more. I also noticed that most of the diesels today on the road here were smoking quite a bit too, like its the city of race tunes... Anyone who has experienced this chime in!
