Hey guys so today I did a wide open throttle pull against a m3. After I left him in the dust he mentioned my car had some black smoke coming from the Exhaust during wide open throttle. I?m currently on map 2 jb4 with downpipes and dci. Is a little black smoke bad/abnormal? Since I have a jb4 can I send a log and have my tune adjusted if it needs it? I just want to make sure my car is running fine. I can also upload the data log onto this thread if that works. Thank you
