Emission delete 6.7 vs 8.3 vs 5.9 Cummins

[CompLexxx]

Hey guys, sorry if it's been posted before, how does an emissions deleted 6.7 stack up against the 8.3 and 5.9, which do you think is best of the 3 (power/reliability/mileage/ease of maintenance) and why? And if you have fuel mileage of a 6.7 deleted please post it up! I'm seeing 12-18 mpg is that accurate?

The other posts I have found do not go much into details or which engines are better for whichever reasons, so hopefully someone can chime in! I am looking at some newer Saf-f-T liners as I love the look, and an wondering if the emissions delete will allow for a better engine and mileage or is it still better to go with older models.

By newer what year models are you thinking?

[CompLexxx]

Newer compared to what people on this forum recommend. 2010-2014

How do you plan to accomplish the “emissions delete” on the newer bus?

No idea with a short bus, but with a full size pusher you'll never see 12-18 mpg, whatever the engine.
