  2. 2019+ General Discussion
    As I was driving down the road after a refuel I normally turn on auto exhaust brake. I track my fuel economy pretty closely, but wondered if maybe I am sabotaging my fuel economy somewhat. So I turned it off. Too early to tell yet the impact. Was wondering if anyone else has already done...
  3. 3rd Gen. Non-Powertrain
    I have an 06 5.9 ccsb with a 2in lift everything else is bone stock (never tuned, stock transmission, pre def, stock exhaust). I’m only getting around 14mpg highway and 11-13 combined. Is this normal? I thought the 5.9 was supposed to get a lot better mpg. Oil change, fuel filter, air filter not...
  4. 3rd Gen. Performance Parts Discussion
    I have a 2004 3500HD DRW. Earlier this year the truck started losing power, blowing white smoke, - and backfiring! - every time the truck would get over ~2500RPM. No codes on the computer. We checked all the obvious places and replaced a few parts before I could find someone with the proper...
  5. 03 - 07 3rd Gen 5.9 Liter General Discussion
    I'm about to make a 2,000 mile trip in a few days. With diesel prices being so high, I'm aiming to squeeze every MPG I can out of my truck and really see what these things can average out. I've got some baseline idea's on how to do it, but I'm open to more. Truck: 2005 Ram 2500, 4x4, G56...

    I will be deleting the EGR from my 2010 mega cab Dually. Anybody who has done this to their 6.7, have you seen an increase in gas mileage or has it stayed the same?
  7. 2019+ General Discussion
    We just tuned our 5th Gen Ram 3500 6.7. This is the first stock truck we’ve tuned. Normally we wait until we do a full delete. I was really surprised with the power sand MPG gains. Check out our quick video on the mpg improvements.
  8. 03 - 07 3rd Gen 5.9 Liter General Discussion
    Why does my 06 5.9 24v get 15mpg with NO LOAD, always now at mostly city driving? Highway is more like 17. My dads ford 250 6.7 1986 gets 25 highway all the time. WHATS UP DODGE!? 1. 06 5.9 24v, mega cab, 4wd, 130k miles 2. oil cap has zero blowby 3. stock rims, stock type AT tires 4. i just...
  9. 2010-2012 General Discussion
    Hey y’all, I have a 2012 2500 6.7 HO, only thing (that I know of) that’s been done to her is tune/delete, 5” straight pipe and a cold air intake. My speedometer is off by a decent bit running 35’s, but for highway whenever I reset my average mpg it hovers around 14 and city it’s currently at 8.3...
  10. 03 - 07 3rd Gen 5.9 Liter General Discussion
    New guy here, new to towing and diesels in general. Just bought a 2004 auto 4x4 with 150000 miles and not even two weeks after owning the truck starting seeing signs of blow by and shop recommended replacing the engine :confused: So now I’ve decided to go all in on a complete...
  11. 98.5-02 Non-Powertrain
    What do you guys get for mpg with 30.5" tires? I have 245/70R17 which is equivalent to the stock 245/75R16 but I can't seem to really get above 18 mpg on average. That's with driving at 65mph constant with cruise control on. The best mpg I've gotten was 21.2 but that was with 265/70R17 tires and...
  12. 94-98 Powertrain
    So I bought my first diesel, a 1994 12 valve 4x4 today. I'm wondering what the best additives to use for fuel mileage are? I know that 2 stroke oil helps, but how much per tank, and does it matter if it's premium or not? Grateful for any help, thanks.

  14. K&N Cold Air Intake with Amsoil Air Filter

    Before installing this K&N cold air intake with Amsoil air filter, I was getting 11-12 mpg while pulling my 8000 lb 30ft travel trailer. After installing this unit, I averaged 14-15 mpg while pulling the same load. I've noticed great mpg gains while under a load, but minimal while running dry.
