Did download without any additional changes yet. Performance has increased. Also sounds better. Very easy to do.

I just dropped the 87 Octane tune with firm shifts and turned off AFM. The truck shifts smoother and it seems to have helped a lot with the driveline clunk when getting back on the gas after slowing down. A custom tune is in the future.
