    Excellent information in this video I recently purchased a 2024 GMC 2500 duramax. It's frustrating to hear people say it's not worth the money compared to the gas when the power output is similar however you made an excellent point that the towing experience is far more pleasant. I have told with many gasoline engines and while it can still tow, it sounds like the engines about to explode as it's working so hard uphills especially in higher elevation

    I am glad you used the cruise control to show what the transmission tuning was capable of. I have a 2023 GMC 3500 and I feel the exhaust brake itself does a very good job, however sometimes the tranny tuning isn't the best and it doesn't seem to be consistant. If I use manual mode the exhaust brake works extremely well. Power wise, I was going to hold out and order a 2024 until I saw the power numbers and the fact that the ecm hasn't been cracked yet, I decided too buy the 23 knowing that I could easily add power. I added a Banks Derringer and Banks cold air intake and I am not disappointed.

    @TDub_ADV 8 місяців тому +1

    Banks did a dyno run on one of these engines that tells the story. According to him "peak" numbers are just for bragging rights and are numbers one will never see in the real world. What he said is this engine makes a lot of actual usable torque to the ground. Too bad he does not have similar dyno runs for the RAM or Ford, it would be interesting to see where they stack up beyond just peak numbers.
    I personally own a 24 3500 DRW w a Duramax and it tows my 5th wheel which scales as 24k lbs. It tows this load very well. I have has no issues towing in places like the Smokey Mountians which has some pretty long steep grades. Engine and Transmission both seem to have very good thermal control and neither gets much hotter than they would just driving around town unloaded. As mentioned in the video i think fuel economy is this engines downside. It seems GM was very aggressive with the regen programing on the 24. according to my Idash mine will regen every 200 miles or so unloaded and about every 450-500 when towing. I think that is what is causing the poor economy overall but if it keeps the DPF from clogging its ok by me.....

    FYI, the gooseneck towing specs you start off with are wrong, UNLESS you have the "MAX" tow package which means the 2500 is built on the 3500 chassis, so they are actually the same. Otherwise, the rating is 19,100, but in reality you have to run the app and see what is it for the VIN, and from several others videos it's actually more like 17,000. This is not a criticism of the truck, but just to get the numbers right.

    • @slidewide1999
      @slidewide1999 8 місяців тому +1

      And with cruise control that isn’t so lazy. In my Cummins powered truck, there’s a hill near where I live that if I set the cruise at 55mph, it’ll lug up at 53 and roughly 1100rpm, but if I bump up the cruise midgrade to 57 it will immediately pull to and hold 55 without downshifting. It’s not necessarily a power issue, it’s the lazy programming of the cruise algorithm.
      But yes, a 10 (or the hopefully pending 8 speed) will finally put the Cummins on level ground with the competition.

    • @diverjp771

      @JohnSmith-ev1sm 8 місяців тому +1

      @@diverjp771 No, it needs more gears because it has such a limited range where it makes power. Right now it is using RPMs that are less than ideal because it has no choice: when it upshifts the next gear is lugging because its too low because the ratios are spread far apart. If you have a 10 speed then the gear ratios are closer, the shifts keep it within a few hundred rpms. Same reason why semi trucks have so many gears, they only have a few hundred rpms to play with so they need those very close ratios.

      Why wouldn’t he use kph ? He is Canadian and Canada and 81 % of the countries in the world use kilometres per hour.
