There are a bunch of different tuner companies out there. I've used Innovative Diesel on my 2 6.0 vans and liked the performance results.
I've been reading about a newer tuner for the 6.0s that seems to be getting great results called AG-Land, but they don't use the SCT x4 tuner.
On the Economy tune and a long trip, I see 16-17. I just made a round trip from Seattle to Coos bay and back with a 5k or so Trailer and got 12.
