Hi..there..

Normally the best place to start checks wise would be the intake system pipe work / aswell as the intercooler pipe work for leaks or any small splits - the fact you have changed the air filter would be one of things to check - the next area id say would be to get the EGR "exhaust gas recirculation valve" removed and cleaned out..sometimes these car stick/or restrict flow and can cause black smoke under load or under throttle or poor performance..so best to have that cleaned out and checked as the next step and see if any improvement is made..I do hope this helps
