Gas Mileage Spartan and SCT...

[Disnitch]

I've seen a lot of guys throw out fuel mileage numbers, but most of you guys have lifts and 37's. Driving normally (not romping on it all the time) what kind of mileage are you guys getting with the Spartan Tunes and the RCD tunes with a max of 35" tires. The most I plan to do (once I actually upgrade to a Diesel) is a leveling kit and 35's, but the first thing I will do is get a tuner and delete the DPF. I'm just trying to get a feel for realistic mileage expectations on the truck...

I drove from Kennesaw, GA to Louisville, KY and got 21.5 mpg hand calculated with the 275 tune in early March of this year. This was on bald 325/65/18 (35/13.00/18) Nitto Terra Grapplers and a 2.5" leveling kit. Around town I see 13-16 depending on the area, traffic, etc. On the highway I see 16-20 depending on my driving habits. 21.5 was the most I have ever gotten with my Spartan setup that I have actually recorded.

10/15 stock, 12/18 with SCT & Spartan both are within 1/2 mpg of each other

around town 14 mpg
highway 16

Hand calculated. That is with the 210, I get about 30 to 50 miles more out of a tank of diesel witht the 275 tune, but the tune shifts so harsh i don't ever use it.

35" tires
20" rims
2" lift

avg around 365 to 490 miles per tank. That is topped off on a 30Gallon tank. The 490 was all highway on the 275 tune. I was getting around 310 miles a tank stock. Job 1 truck.

Gas mileage is the ONLY area I can give an edge to the Cummins... Guys running a Smarty programmer and a DPF delete are getting very good mileage.

I thought we were talking about diesel trucks

It's also an inline 6, instead of V-8 like our trucks, and not to mention the weight difference (Ford being heavier). That helps a little bit with Cummins fuel mileage.

I know what you're getting at... This truck is going to be my daily driver/work truck and I put over 25k miles a year on my trucks. I can't see getting another half ton and getting only 14-16 MPG when I can get better mileage and much more power out of a Diesel. Plus you can't get a true crew cab half ton without getting like a 4' bed. I have friends who can take me to Auction and I can pick up a slightly used truck for a really good price so I won't be paying as much of a premium to get into a Diesel as most other people do. I'm looking at all aspects of these trucks, but so far the Ford is way ahead simply due to the fact that they can make so much power on just a Tune, and more importantly that they can do it without breaking...

14-16 city would be great improvement and worth it IMO.

Damn I would go broke at that rate. I pull 475-500 miles average mixed driving out of mine. Have pulled almost 600 out of a stock 30 gallon tank on the way to the TS event back in may
