The 8HP70 (a8 in scatpack) is rated at 516 tq and the 8HP90 (Hellcat) is rated at 752 tq for one and the gearing is different between the two. Upshift/downshift paddle response is clearly quicker with the ZF compared to the camaro and mustang autos, which can't be tuned to improve. I don't know about actual shift speeds, should be close to a tuned 8L90.
