Title: Audi S6 C6 V10 questions Post by: aef on July 20, 2015, 11:15:53 PM Hi,
couldnt find much about it so far: Does this car have one or two ecus? Quote My opinion based on the Intake from experience is leave the flaps on just make sure they are functioning properly. I took mine off and they made more noise but I also noticed my IATs never cooling off as they should. (the flaps are right next to the exhaust manifolds) When you take them off you lose the suction of the cold air from the grille and I think there is some sort of actual air pump that pumps fresh air into the intake. I replaced the filters with K&Ns and have run both flaps on flaps off and logged runs. My experience is that 0-60 20-80 speeds are improved with them installed. What to do with the broken flaps?

You forgot to mention that this will kill the low down torque on the car. The flaps are there to tune the intake runner length to the engine RPM, which gives a much flatter torque curve. It's not like diesel swirl flaps that are there mainly for emissions reasons. On gasoline engines removing these flaps hurts torque and driveability considerably.
