While I have the 392, I disliked how the valves would close and ruin the cold start sound. I installed the Z Auto modules and couldn't be happier. (y)

I have a T/A 345 A8 and my active exhaust is always open (done by a speed shop). When I startup, I get that high idle than slows down to that lopey sound.
Nice rumble. (y)

This will fix my error code for valves correct.?
Yes, I didn't get any codes when I installed them. And the valves stay open all the time.
