should valves be open at idle?
I just picked up my 2013 ZL1 last week, convertible, manual.
Are the valves supposed to be open at idle? Mine are open at idle, and I can't really claim to hear a strinking difference in sound volume with rpm. I also pulled the fuse, and with no obvious difference.
I am wondering if my valves are not functioning properly, which may not be a bad thing.
