Interesting read:

 

"The 6.6L Duramax diesel engine (RPO L5P) and Allison 6-speed transmission (RPO MW7) available in 2017-2018 Silverado, Sierra; and 2019 Silverado 2500/3500 and Sierra 2500/3500 models have several different operating characteristics when compared to the previous generation powertrain. Some customers may notice these differences if they owned an earlier 2011-2016 Silverado or Sierra diesel-equipped model.

The new 6.6L Duramax diesel (Fig. 9) shares only bore and stroke dimensions with the previous diesel engine. It features a new GM-developed control system with an electrically-actuated/electronically-controlled turbocharging system and an advanced solenoid fuel system."

Yup.. look at that catalytic converter attached to the turbocharger .
The converter can run hotter and be more efficient .
