Hey Guys, I have a 2006/2007 GMC Duramax with Banks Big Hoss package and the super scoop air intake, and I passed smog test in California, (with a little help from Sacramento),with the six-gun tuner and IQ installed. That's a testament to all of Banks research and testing.

 

I have a 2007 Dodge Mega Cab, 2500 Cummins 5.9L daily driver truck that I am looking to upgrade. What you have done on your truck is similar to what I am planning.
My goal is focused on improving fuel efficiency while remaining quiet; not horsepower or speed (I haul rarely). Albeit, each will likely improve as the engine's efficiency is upgraded. Currently, my stock truck is at 19 mpg, I want 35 mpg.
Overall for upgrades, I want my engine to breathe better- more cold dense air in, and less restrictive manner to get the exhaust out.
The four Banks items I am looking to upgrade with are:
1/2- Banks Ram-Air Intake System with Banks Super-Scoop Kit,
3- Banks Techni-Cooler System package (but with the 3 ˝” mandrel bent boost tubes from the ‘42766-monster-ram-intake-w-boost-tube-2003-07-dodge-5-9L’ package), and
4- Banks Big Hoss Intake Manifold System.

Four non-Banks items I'm drawn to for upgrades as part of my plan are:
1- BD Ported Wastegate T6 exhaust manifold,
2- Turbo Smart Hyper-gate 45mm,
2- MBRP 5" Quite Tone muffler exhaust system, and
4- Wicked Wheel 2 or another turbine wheel upgrade to pull in more cold air

Is the package I am putting together on track to improve fuel efficiency?
What advice can you offer to help me reach my goal for increased fuel efficiency?
Do any of the Banks or other products I am planning to partner together not work well together?
Does the Super-Scoop Kit ever lead to water intrusion into the intake? If so, are there cheater tips to prevent this?
For programmers, is the Bully Dog GT good for what I am working to accomplish? I had one given to me. So no skin in this model if it isn't what I need.

Thank you for your time.
