Re: 6.0 Fuel Mileage??
Put a 4"turbo back exhaust system on the truck. If you can omit the Cat
Converter do so that will also help. A straight thru design muffler is also going to help with EGT
Make sure fuel pressure is 50 PSI
or better and make damn sure turbo is freely adjusting VGT wise.
Then a FICM
Atlas40 will likely give you a few MPG
gains. Also a good ECM tune will likely help with mileage too as long as its no aggressive.
Now heres something that doesn't come easy but with my 38" tires I average 17MPG and that is exactly what I'm averaging. On the highway if I'm trying really hard to be good I can get 20 mpg
on level highway at 65-70 mph. But I am emission free engine has been rebuilt o-ringed and runs better then new. Also the 38" tires are 105 lbs each along with 20 lb
wheels so at 125 lbs each once they get turning a flywheel affect surely plays a factor here. My truck just lumbers down the road almost effortlessly.
So lift it 7" and toss on some big rollers. Will only need to drop around $7,000 to get it where my truck is today. lol
But not many like jacking their truck up to a point where it sucks to get in and out, so take that with a grain of salt. Maybe a bowl full of salt
