yes change the engine type to a 6.0, and if you havent already, you will need to adjust the displacement above it. The PCM uses this for fueling and other calculations.

I'm not sure exactly, i do know it uses the cylinder volume to help scale some of the tables in the pcm.

I would think your AFR would be calculated incorrectly as well as IFR and PE if the displacement didn't match the actual engine
