This is the biggest thing keeping C8s, and 2020+ GT500s, slow. People have thrown tens and hundreds of thousands of dollars at C8s, but the DCT lockdown is the limiting factor. The TCM notices any additional torque and just kills things. I mean, look at GT500s, they need like 1,000-1,100+hp to go 8s. The fastest GT500 needed to go TH400 just to get away from trans limitations.Recently saw an IG video with C8 owners lamenting about the struggles.
The PCM is largely cracked and open but they're still dealing with severe issues with the "TCM" for the transmission (which is still very locked). So basically you can spend a bunch of money upgrading your power plant and tune it but it ends up throwing the car into limp mode quite often because of the torque protections (not unlike the GT500 in some situations). Apparently you can upgrade clutches and add some piggy back modules to trick things but it still doesn't fully resolve all the issues.
4 years later and the car still isn't fully open for unlimited modifications. It's unclear how much of the stand alone market is available to them, but it's got to be better than the 16 injectors on the late model coyotes.
