My latest Dyno below... results are entirely thanks to ADM Performance. No one else will ever work on my car, and if they don't make the mod then my car doesn't need it. Andy has my L99 running some incredible times and numbers.
NOTE: The earlier run was my car as GM sent it to me... that is to say, before any efforting by ADM Performance... about 3 months ago. The second run was today.
