This sounds like you're just seeing the affects of running no cats. It's completely normal! The exhaust is very free flowing now so it's just dumping anything that the cats would usually catch out the exhaust.
If you'd like us to look into your tune to make sure it's not running to rich, we can do this for you as well. Just hit up the Bama team! Our Bama Performance tuning specialists are here in the building Monday-Friday from 9AM-5:30PM EST and Saturday 9AM-5:30PM EST. You can hit them up directly at 888.226.9764 and they'll get you squared away!
