The 6.4 is a very capable engine, but I have some doubts when you start to tow heavy at elevation with anything normally aspirated. How much do you plan to tow because you do have some elevation in ID?
The elevation thing I believe may be a major issue here in comparing the 6.4 to the Cummins. Thanks to the OP for running these tests and posting them, but it would be awesome if someone would run a similar comparison at 5000' or better 7000' elevation.
I came from a diesel to my 6.4 Hemi and was worried about the elevation thing. I recently hauled my 8500# TT and a truck full of kids, bikes and firewood up over Mount Hood in Oregon and felt very little drop due to elevation. Granted, it's only about 4500 ft but is pretty quick/steep getting to the top. I ran through the scales and I think I was about 17,000# total.
Overall, I'm more impressed with this truck every time I tow with it. My last truck was an 06 Duramax which was great.
If I regularly towed over 10,000# I'd probably opt for a diesel but for med/leaning heavy towing the 6.4 is a great truck.
