New Ram/Cummins vs GM/Duramax on the IKE

This conversation should be about the Duramax L5P and the current cummins with the CP4 and reduced compression. I'm hearing reports that the latest cummins is making less fuel mileage than the previous generation and maybe requiring more turbo boost now to make equivalent power.

Can you please post any links where you have been hearing these reports? I would love to read them because some new Cummins owners like Lavon Miller at Firepunk diesel has been doing video blogs about his new 2019 Cummins he just bought with dyno and others tests comparing it to his 2017 stating otherwise.

Also, reduced compression is likely due to the increase in fuel pressure coming from the CP4.
