I have a 2011 stage 2 custom tune some one today told me getting black soot I'm running catless downpipe and straight pipe would that be the cause or the tune. Eric is the one done the tune

Sounds like you are running too rich. Not completely out of the ordinary, Especially if you have a catless downpipe and a BOV. The richer your tune the more soot you will see. Do you happen to have your BOV set to fully recirculating or atmospheric? Are you still getting any of the backfiring you were getting a while back? Are you getting actual deposits on your bumper?

Nah. Running too rich typically causes problem over the long haul. Running too lean is what causes sudden catastrophic issues. A few pulls won't be detrimental if you're just running too rich.
