Issue with Corsa valves closing in Sport/Track/v mode when decelerating

[SocalBlackwing]

Anyone install Corsa Extremes and have an issue with the Valves closing in Sport/Track/V mode?

Valves also no longer open on cold start.

Tried to perform the Valve Relearn and no luck.

Anyone have any idea what the fix could be?

Scanner shows the position at 10% then goes to 80-90%.
Valve state shows out of range/ unrecognized state…

I installed a Corsa cat back set up on my 2024 CTS5V BW and immediately had valve issues and check engine light.
Tried re learn, and hard reset everything, finally after 40 ish days I told Corsa send me return label this stuff is coming back.
They immediately said hold on we have a new valve set up for the car and sent me 2 new mufflers, installed them cleared the codes all good.
Now even in race mode, when i pull out (Manual) and or back up for some reason car will get quit and then they' reopen. I assume it's something with Timing and back pressure needs? just a guess
Do you HAVE CEL light?
but when it starts, they are wide open, to me it sounds like you have about same issue as me, the old mufflers would not open correctly 1 would 1 would not, in race mode 1 was wide open other about 60% and they would close when car was shut off.
