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.

His stock 2019 Cummins rated at 400 hp/1000 tq made 392 hp and 896 tq at the wheels on the dyno. He says his 2016 truck (385 hp rating) made 342 hp at the wheels.
VIDEO results start at 8:52 in the linked video.

385 hp rated made 342 hp.
400 hp rated made 392 hp.

15 hp increase in rating but 50 more hp on the dyno? Is Ram sandbagging the numbers?

If this new cummins HP is understated then one can say that about the Duramax used in this test.
