Heavier trailer, loaded with TC, Better MPG... and pics

Finally got the projects on the new trailer done, as well as a couple truck upgrades, so I went out for a 4-day boondock run. Went to a little place to go play in the sand called Beverly ORV Park, just south of I-90 near Vantage. Ran 3 passes, Tiger Mtn, Snoqualmie Pass, and our notorious "Vantage Hill" (otherwise known as radiator hill).

Truck changes done this last couple weeks-- Banks Quick Turbo kit that involves new exhaust-side housing, compressor side wheel, and new Big Head waste gate.

New trailer - replaced a 20' 7k lb Interstate enclosed trailer with a shiny new 2015 26' 10k Wells Cargo. Put a 19' motorized awning and 550 watts of solar on it, equipped it with three 145aH batteries, beverage fridge and freestanding icemaker.

So - new turbo and cold air intake - clearly, the PCM/ECU had to learn a new airflow/fuel curve. Initially, I thought, man, what a waste of money, less boost, higher egts. But after about 30 minutes it started to come alive. I have more power, and better MPG. Pulling all 3 passes, I gained on average 5mph, and at the end of this trip pulling all these passes I used to average 7.5mpg, fill up/calculator method had me now @ 8.7mpg -- and the trailer is 1,500lbs heavier.
So -
Trailer is 1,500lbs heavier
Gained 5mph pulling hills
Gained 1.2mpg, from 7.5 to 8.7
Cruising flat 60mph - boost came down from 8lbs to 5lbs, pyro from 850 to 750.

Worth noting - my mpg is not that bad when running on the flats, it's the 3 passes that kill it whenever I head east.

The new trailer hauled like a dream... I have the 42" Torklift truss, had to make several sharp turns to get in and out of the fuel stops and campsite, no issues.

Some pics of the place---
It rained for 3 days straight before I got there, hence the muggy, and the big puddle under my truck (and NO, that's not me pullin' the tank handles)
