People claim my 10 speed 23 zl1's feel faster and are faster 60-130 (6-7 sec vs low 8's) than previous year 10 speed auto zl1s. Ive seen some claims that 2023 zl1 dyno at 590 and previous years at 530-560 hp) 2022+ gained pankl rod I believe. Ive heard some claim the supercharger in 2023 gained vacuum bypass vs electric in older years.
