Question on Electric Brake Boost
I have only owned my C8 for three weeks now. My question is on brake feel. When approaching a stop, even light pedal pressure will cause an momentary "aggressive" initial bite (jerk). I don't know if that's when the boost is initially applying the pads to the rotor. It's not excessive but I cannot lightly apply the brake pedal without feeling that little jerk (flamesuit on). 
BTW, I have tracked my C5 for nine years, and have a good understanding of brake feel.

I don't have that issue on my 2021 non-Z51. I can modulate the brakes without any problem. What drive mode and/or brake setting are you using? Tour requires the least pressure, so maybe a little harder to modulate than Sport or Track, but I don't have a problem even in Tour. How many miles? Maybe with a little more bedding in they'll smooth out.
You have followed the break-in instructions to not aggressively use the brakes for the first 500 miles, right?

Unfortunately, I am not the original owner. I bought this with 3600 miles on ot. I cannot speak to the brake "break-in" process.
