I guess what I'm trying to say is....suck it up and fill the tank.
How you gonna come on here and say I got a 418Ci, turbo, 14bolt, on 37's...how do I get good gas mileage?

Just want to get the best possible thats all, after this round of **** there aint much else I can do to it drivetrain/power wise which is a GOOD thing. Then I can start working on the looks a bit more, hopefully this time next year I will be done with it and can move on to getting a house.

If you're going with 35's tires i'd go 4.10 for 37's i'd say 4.56.
With the mods in my sig I get ~17-18mpg highway driving unloaded with small hill climbs here and there. City, about 13-14mpg if i can keep my foot off it. Towing a 5-6K boat fully loaded i get about 9-10mpg mostly highway driving. Don't get me wrong, I LOVE the power and torque off the line with my 35's and 4.56 gears (especially off-raoding), but i do mostly highway driving ~85% and i think if i got 4.10's i could be getting a little better MPG. Around 70-75MPH ~2200PRM is the "sweet spot" for my truck where it feels like it's not lugging or pulling hard, but has the potential to pull if i step on it.
Hope this helped.

By the way with a 6" lift your not going to fit 37's unless your sawzall has a Big blade. So after all this rambling I guess I would say 35's and 4.10s.
