Programmers

[shofrothjr]

Wondering if the BullyDog programmers do any good for gas engine trucks.Looking for more mpg out of my 08 Hemi dodge 4x4

What is the fuel mileage now :?:

[shofrothjr]

About 16 if I drive easy,same as my 07 GMC

[mopar1968]

You have something else going on, Is your engine MDS :?: What year is it? Those engines should get between 18 and 22 MPG . My brothers get's 21 here in the mountians. My Cummins gets 23 here in the mountians.

I just got it,it might be close to that,thats what I was told.Either way just exploring ways to get more ya know.I know the programmers are great for diesels just never had 1 on a gas motor

Oh yeah you can put one on a gas engine but how they do on fuel mileage i really don't know. I work at a Chrysler/Dodge dealership. I have wondered how they help on a Diesel with all that black smoke myself. A Diesel blowing black smoke is just unburn't fuel, Too rich. But remember too lean and you will melt that engine down :!: :!: Right now engines are running as lean as they can thanks to our wonderfull federal Goverment :!:

Ive tried Bully Dog, Hypertech, Diablosport and a Hyperchip on my 2500 hd. Bully Dog didnt do s#@t besides drain my pocket same went for hyperchip. Diablosport had a increase in mpg, but in the end i went back to the one started with it is the hypertech e-con save me a average of 3 mpg. Deisels i have heard bully dog worked well.

got the diablosport in the 6.6 duramax in the 4x4 3500 dually crew cab and it works great... in tow mode .... it will pull a frigging house down and with the 125hp program in it... she will just pin ya in your seat :) get 20 to 21mpg in reg mode and 45 to 50 in 125hp mode.. pending on speed. over 70mph it drops of alot

45 to 50 mpg??? :shock: I want one of those!
My 05 duramax with 207,000 miles still gets 20 on the interstate.
And you are right much over 70 makes a big difference.

hell yeah... best investment you will ever make.... :) i had it as high as 59 mpg but that doing the speed limit and running cruise control.... but what fun is that.... lol

I have used the diablosport on many vehicles and it is a great tuner for the duramax but we found the edge products was our choice on the duramax little easier for tuning we thought.

I've owned alot of trucks, all different brands and if you keep it under 70 on the highway and don't jack rabbit start in town you will get the best mileage. My 2007 Cummins lost 2mpg from 68-72 mph.

I will agree the best way to save gas is training your foot to stay out of the loud pedal!
