air filter
do the s80's have a noticeable improvement with a K&N filter? do they make them for the S80?
my next question is about wastegate's... if the wastegate is set to dump boost at set PSI then would you get more power/boost if you kept the waste gate from opening or if you were to delay it?
thanks
