Do you get any smoke when going full throttle? Before chasing a mechanical issue (leaking injector, turbo seals) I want to make sure it is not just smoke from being rich on spool up. It smokes when I go full throttle for a quick second and then goes away during the rest of the pull. I do not remember any smoke when I was running the JB4 but I could be wrong. I will try to take a go pro video when the weather clears up. I have catless downpipes but still have my secondaries. I found a video that @JStang posted and his issue looks identical to mine. Here is a link to the video http://www.e90post.com/forums/showthread.php?t=864137 . If it is normal I can live with it I just want to make sure I do not have a mechanical issue. Here is a recent log
