I have a 2005.5 Audi s4 b7, 4.2l v8, I get a quick power increase at 5000 rpms and irk what it is
as in the car gets more gas on its own? when you do this do you put your foot to the floor ? because the car has a little button on behind the peddle that kicks the over drive in and shifts it down in gear for most audis in auto mode.
PROBABLY the intake flaps changing over to provide more airflow
