I got in contact with aem again. They wrote back after looking at my idle logs, and they think that my car is missfiring and not completly running on 3 cylinders. I got some tests to do and some changes to make in the session. Hopefully Friday i can sneak into storage and try them out. That could possibly explain my black smoke during a pull. I know what the car sounds like missfiring, and it should be clear during a pull. *shrugs*
