the computer was for the 5.3 dbc and it did originally have a 4l60 but was no good so i swapped it too a 4l80e, I had a stand alone harness built for the engine with the 4l80 transmission as far as tuning goes it was done by a local guy that did a base tune and he said he set it up for the 4l80, i know nothing about tuning so i'm just going by what he said.
