as far as I know, the exhaust valved are either open or closed. dont think theres a setting for anything partial open.

What i do know is my car has more "crackle" in it after the tune..

NOTE: I do have an aftermarket Fabspeed Exhaust. It was already loud with lots of crackles before the tune. However, the tune makes more popcorn.
