Smile Fuel mileage update

Just got home from cross-country road trip. 8700 miles in 14 days!! Overall mileage(miles/gallon on calculator) was 19.2. 2010 F350 6.4 extended cab shortbed w/ cap on. On board computer is definately a liar, as it read 23 mph.Much of the time was at 80mph w/ AC on.

Equipped w/ Gear Boxz DPF_R plus economy tune, EGR block off plates and AFE 4" exhaust (downpipe back) w/ muffler supplied.
Much more power and fuel economy(without regen)
I'm lovin it!!!

Thanks for the update!
Any more feedback since last month? Any rants or raves?

How much smoke is there?

Any recommendations of where to get a setup?

One of my coworker's got one of these Gearbox Z's and he said it was a big ol pile of crap. He took it off and replaced it with a Spartan and says it was the smartest thing he ever did.

The fuel mileage is good, but the big plus is no more fuel in the crankcase. Your motor will thank you.

I was only looking for DPF delete & fuel milage. I got both with no trouble and no codes. I"m happy with it.

How much do you think the intake helps, and is it a worthwhile investment?
