My 2008 pre spartan was getting 12.5 MPG and now with the 275 I can get 21 and 25 with the 310

I am not "on it" to get this. Just cruizing at 75mph It goes up from there if I do 55 But I can't ever stay there.

Thats 275 and 310 power gains? That is amazing mileage. Is that a safe tune? I guess I'm really behind on the tech for these motors.

I have 64,000 tuned with 275 and 310. I dont run 310 in the winter or as a daily driver but it's fun for the weekends.

21-25? Is this hand calculated or using the Lie-O-Meter?

Hand Calc Computer tells me I am getting 30+

Is that MPG or KPG?

30 is a very big step forward from the 14 I'm getting at 70 MPH, stock and not pulling anything. Maybe I need to consider some mods after all.

I have an 09 F250 6.4, Shortbed, King Ranch, running FULL Ranchhand steel bumpers (about 400 pounds), and a Leer Fiberglass cap

with the 210 Spartan tune and replacing the DPF/CAT, I get 19 MPG on the highway (drove 125 miles, around town all day, then back 125 miles). I feel if I bumped the power up I would get better mileage, or if I drove further.

Before the tuner I would see 13 MPG on the average.

What did you replace the DPF/CAT with: straight pipe or something else?
