Should I upgrade?

I currently havea 03 6.0 with 111,000 miles banks six gun and instake and i did the exhauset myself. I have been thinking for a while about upgrading to a 6.4. I have seen alot of guys online running 6.4 with spartin tuners and AFE intakes and 5 inch straight exhaust DPF and EGR delets, is it all worth it? Will i get better millage, power, and drivability from a stock 6.4 to a modded 6.4, is it better then the 6.0?

Any answers are welcome

Mitch

from what I've read on here, and by what I'm seing so far with my spartan, that's about what you'll get with a modified 6.4.(roughly, depends on gears also)

My 05 350 6 speeder would get 20-21 on average empty and aroudn 12 with a 6k load behind it.
The "new" 08 450 stock was looking at 10-12 and now after soem tuning and allowing things to walk away in the exhaust system she is looking at 16-16.5 on winter fuel. Gonna leave the hood open one night and see if the EGR will bolt for freedom as well.

Mods H&S tuner running the Hot tune
5 inch sewer pipe from Flo-pro w/muffler
Volant CAI with the Donalson Filter

Next Steps

Custom KEM tune for the trans
EGR delete with wastegate
Airdog
....

PS I drive like an ole lady to get these numbers.
