i have a 03 a4 1.8t quattro. i plan on getting the chip but i know i need to upgrade the dv first. i was wondering if these motors have problems with a atmospheric bov rather than a dv? also it is an automatic,can you hear the aftermarket dv's on an auto like you can a 5spd?and before people start flaming, im not looking for a loud ricey bov. im just wondering what my options are.
