I have COBB AP, is there any way to code it via a COBB custom tune? I want it to be open in all throttle situations above 40% and/or 2500RPM, in other words no loud exhaust when cruising. My setup is going to be very similiar to Akrapovic's, the two inner tips will be muffled while the outer two will not be.
