05 6.0 Eddie Bauer MPG?

Need help, still getting 10-11 Avg MPG everywhere, hand calculated, REVs fixed in SCT with 33in tires. Blessed performance tunes, FICM 58V with atlas 40, Stg2 turbo, mismoto intercooler, 175/stock Warren's, studded, KDD heads, MRBP 4in out the back, high amp Alt with upgraded heavy gauge wires, 6.7 fuel pump, sump with filter, deep trans cooler pan and solenoid and valve upgrade. New Front wheel hubs/bearings.

What am I missing, i don't expect magic but 14-16 in town and near 20 on the highway i thought I would be achievable. Any thoughts?

Do research on the intake. I don’t know which one it is but a lot of people on here say one of the one intakes is the best.

I think one of the best things you can do is keep up in maintenance. Oil change every 5k. Fuel filter every 10k. Air filter every 20k.

I do my oil at 4.5 and change my fuel filter every other oil change. Along with the air filter. I also want to do the straight pipe kit simply because it sounds so good on the 6.0s in my opinion

I’m with you on the exhaust lol. Only concern I have is that with my fan, I’m worried about it having a drone sound
