I just picked up 2022 Longhorn 5.7L MDS VVT e-torque Hemi, 3.92 diff. 27K package, HUD and safety option, level 1 package with Coil spring suspension. My first truck was a Ram back in 1980 (yes I'm that old, lol). my second was a 360, all were 1500s. It's good to come back home, and I'm not disappointed! Yes, it is essentially a 2021 with a few bells.
Engine Break-n from the manual.
"A long break-in period is not required for the engine and drivetrain (transmission and axle) in your vehicle. Drive moderately for the first 300 miles (500km). After the initial 60 miles (100km), speeds up to 50 or 55 (80-90km) are desirable. While cruising, brief full-throttle acceleration within the limits of local traffic laws contribute to a good break-in. Wide-open throttle acceleration in low gear can be detrimental and should be avoided." p151.
So my best guess is:
So, some brief spurts of acceleration (after 60 miles I assume) seating of the rings as usual. I assume the vehicle should be driven on the gentle side for the first 300 miles. I have taken it on the freeway twice within the first 60 miles (my bad), but kept the speed at or below 60. I'm assuming from the manual, it may be best to keep the vehicle at 50-55 or lower until I get 300 miles on it. A.K.A. stay off the freeway for your first 300 miles.
While I've read others feeling things being a bit rough on the low end, I have been gentle with the low end from the beginning. Mine had 12 miles on it before I got it, has about 60 on it now. I've noticed that as I continue to be gentle with starts from a dead stop, It is smoothing out. I was glad to hear someone else mention that they probably have a chip that is learning how I drive but also trying to optimize everything that is going on. The MDS VVT trying to work with e-torque is a very sophisticated system that contributes to your fuel economy, power, and smoothness of ride. Seems reasonable to give it a chance to figure out a few things before I start putting my foot into all that torque.
