    Same here. I kno nothing about the workings of cars but im guessing something to do with when the  un burnt fuel is dumped? Hence the pops and bangs?

    It’s normal for the Ecoboost engine, a trait of direct fuel injection to the cylinder.  I had it on my ST3, looked into it at the time.

    The pops and bangs will also contribute – it’s why you’ve probably noticed the back of the RS gets a dirty aRSe quicker than other cars you may have owned :D.

    My old Impreza had antilag with an aftermarket ECU (as opposed to the fake pops and bangs you sometimes get on the standard ECU flashes) and the rear bumper was constantly filthy!

    Perfectly normal just probably the standard map runs quite rich, infact even a mapped car will still get it. Just coat the inside of the exhaust with a sealant when new so its easier to keep clean
