You're NOT serious are you????????????????????????????I just bought my 2021 Ram 1500 Big Horn and I'm interested to know how to run on 4 cylinders all the time, to save on gas, and how to change it back to 8 when I want the power. Any assistance would be appreciated.
Thank You!
In reality you would more likely to suffer increased fuel consumption by constant four cylinder operation. Trying to move a 5000+ lb. vehicle with half the displacement of the 5.7 Hemi would likely mean you would be using excessive throttle pressures to accelerate and maintain speed.I just bought my 2021 Ram 1500 Big Horn and I'm interested to know how to run on 4 cylinders all the time, to save on gas, and how to change it back to 8 when I want the power.

This isn't actually true - when you switch to MDS, those 4 cylinders will run at higher load. That load transition is why there's a "bump" - you're switching from 8 cylinders putting along to 4 running almost as hard as they canIn reality you would more likely to suffer increased fuel consumption by constant four cylinder operation. Trying to move a 5000+ lb. vehicle with half the displacement of the 5.7 Hemi would likely mean you would be using excessive throttle pressures to accelerate and maintain speed.
The MDS system was not designed to be anything more than a supplemental fuel management approach under no-to-light load conditions.

Turn off MDS?Dang, I wish I could “force“ my Ram to run on eight cylinders all the time,
That's what I was going to say (but didn't). Almost like we're being trolled. BUT, it got people to responding.This can't be a real question

Guess it makes some people feel superior to step on others. There really is no "perfect", otherwise we would all be driving the same identical vehicle, living in the same identical house, and agree with everything that everyone thinks, says, or does. How boring. But, then again, some are just up for an argument no matter the situation.I find it strange how upset people get at the idea someone might want to run in 4 cylinders and be more efficient with their truck - will never understand why others seem defensive about it and feel the need to question the validity of the question. My 1st ram had the V6 and it was a great truck that did everything I needed and used less fuel doing it. My last 2 have been Hemi trucks because I couldn't have a CC and 6'4" bed with a V6 and that combo was important to me. I would love a truck that could run on fewer cylinders in daily driving and more when I want fast starts or heavy towing like to OP is thinking. My truck is in Eco mode at least 50% of the time in both city and highway driving so it seems to work well. In the end I think the V6 is the perfect mix of mpg and power for 99.9% of truck users who don't tow more 5,000lbs.
