What gears will work best?
Brother-2003 Supercrew w/K&N, Exhaust
Mom-2003 Harley-Davidson supercrew
Dad-2003 6.0L F-350 w/6" exhaust, Poweredge chip & propane.
I currently own a 2001 F-150 Supercrew with the 5.4. I put a new throttlebody, throttlebody spacer, K&N, Magnaflow exhaust, and installed a superchips programmer.
The problem I am seeing is a lack of low-end grunt with 3.55 gears.
What will be the best gearing option to make the best use of my power upgrades with 285 BFG tires?
The only trade-offs are worse gas mileage and higher cruising rpm

The 3.73 may be a good compromise if you care about the above things. If your world is the stoplight grand prix, then definitely go with the 4.11.
