Turn off the DOD.
Displacement On Demand.
When the ECU deactivates cylinders. It beats the hell out the motor.
Lifter issue solved. Can’t be done on the ‘22 refresh and up. Existing controllers on the market won’t work with them No ‘22 refresh has DFM…and they even paid me $50 for the “inconvenience” Actually only a few of the early ones had it deleted and it was just the computer controlling it. The rest of the components such as the lifters are there and it can still fail like the rest. You just got paid $50 to get less fuel economy

You do realize the refresh was mid cycle right? The “early ones” were ltds

Chevy is not having issues with the new 6.6 Liter Gas Engine. It it the 6.2 Liter / lifter issues. this is correct...my 6.2 crashed the lifters at 12,000 miles. Ugh that was frustrating but I do love the power.
Whether you think you can or you can't, you are probably right.

I’ve had both 5.3 and 6.2. I would buy the 6.2. I run premium in the 6.2 but it actually gets better gas mileage and out performs the 5.3.
