You will still need to pay for an extra tune and a dyno for the engine. Holly EFI won't support the 8spd just keep that in mind

do you know if the terminator will support it? I remember watching the Holley Hemi swap Dakota video and they said the ecu could control the trans as well, or is it that it doesn’t support the ZF8

To my knowledge no because the ZF needs the torque and hp curve programmed into it. Also running that you won't be able to use your stock gauge cluster
