Been a busy summer/fall and finally getting back to the forums here. Have some upgrades in-progress for the truck, which I'll be documenting here.
In completely stock configuration and with, I got 18.4mpg running 68-72mph on the 300-mile trip home from the dealership where I bought the truck last January. This summer I was able to get a better MPG test after adding the Bilstein 5100s up front, larger BFG KOs, a Magnaflow catback exhaust, and the Omega tune from Oz Tuning. (Also running the AEM drop-in filter, but no CAI.) This isn't a commuter and I don't drive for mileage, I was curious to see some MPG comparisons after the updates. On a family vacation this past summer we covered 600 miles each way. This was with 2 adults, 2 kids, coolers and other gear in the bed, and a LOT of gear in the Decked system. So with with truck updates and the added weight compared to my original trip home from the dealer, I was curious to see what my MPGs would be.

On the 600-mile trip up, I ran conservatively and kept it at 68-72mph, which averaged 19.4mpg. Same speeds as "original", considerably more weight, but exactly a 1mpg improvement. For the 600-miles home I ran 73-77mph, which averaged about 18.9mpg.
I am happy to get better MPGs with the tune, but more than anything the driving experience improved phenomenally. I knew I wanted the Coyote and I am glad I got it, but I knew it could be better. I drive a lot of local roads, which have me cruising between 30-45mph often. The shift points, especially for that type of driving, left me unimpressed to say the least. Sport mode helped, but it also had quirks. I found myself going in/out of Sport mode and manually locking out certain gears quite often.
That got me looking into the world of tuners and custom tunes. After a lot of research, I pulled the trigger on the Omega tune from Oz Tuning. The Omega claims to be a "one for all" tune, instead of offering an economy, a tow/haul, a performance, and octane-specific tunes. It sounded too good to be true. A lot of guys seeking high-end performance touted the praise of the Omega tune. But I wasn't trying to get my truck to run a 1/4-mile quicker. I just wanted it to be more drive-able.
Having run it for many months now, I am really impressed with the Omega tune. Anytime I began to think "I wish it would...", my truck did it. Shift points, power, RPM management, etc. This is the 5.0 the way it should be.
