I've recently purchased a 2006 B7 RS4 Avant after a long time looking. The one i ended up getting came with a fair few optional extras

It has the following mods/optional extras already:
-Carbon ceramic brake package
-Porsche oil and coolant caps
-carbon interior trim
-LED upgrade to all interior lighting
-RS6 wheels
-Bilstein coilovers all round
-MTM Exhaust
-MTM Supercharger kit
-twin plate clutch(brand unknown)
Things I'd like to sort out in the near future:
-head unit upgrade( if a direct upgrade exists- recommendations ?)
-bit of paint correction and a couple of small dents to be removed
-replace factory intake with something aftermarket ( any recommendations ?)
I have noticed that it runs a bit rich and the cold start is a bit rough, so im not sure if whoever installed the supercharger kit fiddled with the tune, but I'll have to get it onto a dyno to suss it out.
Not sure how many others have the MTM s/c kit on their RS4 but I'd like to know if the Sport mode still has the same effects now that the car has the MTM ECU - the exhaust flaps do open up, but i'm not sure if thats all it does at this stage ( the throttle does feel more responsive in sport mode).
I've added a couple of pics - the day i got delivery, First wash and one of the engine bay
