Is it worth it?

My 2011 F250 is my first Ford diesel....I'm wanting to do a programmer, DEF delete, exhaust, EGR delete & intake. I've read all the threads on the brands... I'm leaning H&S on the programmer.
My truck has 55k miles on it and I've had little problems out of it... just some factory recall stuff.
My question is.... will the mods greatly improve my fuel mileage? The stock truck has enough power for me in stock form.... I just don't care for the DEF stuff. Plus I miss the smell of diesel exhaust... LOL!

I get 16-18 mpg stock. With my tuner, DPF on, I've seen 20 once but usually still 16-18. When I had DPF off, I saw 20 more often, but usually around 18. Not a huge mileage gain, but it was noticable. H&S is what most people seem to go with. I've been happy with H&S on mine.

You can't expect huge gains from the 6.7 in fuel mileage because it doesnt use fuel to regen like the 6.4 where some would see big jumps in mileage. Your mileage may get a little better due to a more free flowing exhaust and a little more power with light foot could get you a mpg or two. Some feel that power and are always stepping on it and end up getting worse mileage. What you gain the most from those mods is more reliability since the emissions systems seem to be the number one cause of failures on modern diesels.

6.7 and 6.4 regen the same way. They both inject diesel on the exhaust stroke. Only difference is a 6.7 has urea for the NOx.

Really? I guess I need to do more reading than assuming lol. Then how does the 6.7 get better gas mileage if they regen the same way?

Transmission......

I run the H and S 5'' pipes and we ran last saturday to Baltimore from Seaford DE on HOT setting round trip was 220 miles and we reset the trip and fuel milage estimator before we left and we got 22.6 to a gal NOT BAD but then again i was not playing like i usualy do

[redrider8293]

The reason the 6.7 gets better mileage then the 6.4 is because ford changed the frequency the regents occur I believe the 6.7 regents a third the amount of times as the 6.4

The 6.7 only uses left bank of injectors during regen and can do passive regen. The older ones used all injectors on regen and would have egr problems thats why only left side on 6.7. Plus with def allows engine to run hotter and still meet emmisions.

my 6.7 sees regens 100-250 miles more average 150ish
