Abuse mode as well as the traction control don't like you power braking.

Try it with the TC off

Abuse mode in pcm cuts power at 1200 rpms by 50 percent. I have turned my traction control off and still does it. Been discussing it here https://www.corvetteforum.com/c5-scan-and-tune/3475707-please-help-cant-build-up-or-spin-tires-over-in-my-c5-corvette.html
