Honest Hand Calculated Fuel Economy On Tuned 6.4

[ThirdCoastStroker]

I would like to see honest (no bs'ing) hand calculated MPG on 6.4's that are tuned...i will be tuning my truck and deleting dpf going straight pipe as soon as my warranty expires at 124k i am at 82k now...i would like to know what kind of mileage you guys are seeing and what tunes and tuners you are getting them from.

thanks in advance

I get 15.75 often in the city. I accelerate quite a bit also. I run the spartan 250 tune. On the highway i kiss right up on 18 sometimes, but i'm always running 80-85.

Towing the boat it dips to 12, but I baby it.

stock im getting on average 11.95 mix of hwy and stop and go

and it pretty much blows....

I will post in a couple weeks what kind of improvement I am getting. I ordered a spartan, delete pipe, and cold air intake because I was tired of poor fuel mileage and want more power for pulling my camper. Stock I am averaging 12-13 hand calculated and 7mpg pulling an 18k pound camper so it's got to get better.

Yeah i feel ya there i pull a 30ft gooseneck with a 100 horse john deere and a bat wing shredder i usually pull it about 100 miles max at a time so i have never got a good reading for mileage with it i just no i sucks that diesel down....at 70 mph i can almost watch my fuel guage drop!!!

I would like to see that mpg as well. I am in the same situation as yourself I have an 08 with 19K left until warranty expires. Also, When you guys mention cold intak are you just changing the intake to an S&B, AFE, Banks, etc.?

[white05]

I ordered an S&B intake with my programmer and delete pipe. I only have 8500 miles on my truck so hopefully I don't have any problems.

I'm getting 1.5 worse tuned than stock, total BS.

I get 13 all day no matter what I do . This is not towing. This is with everything in my sig.
