If the 440 hp rating of the Powerstroke is not SAE flywheel hp what else would it be?

I have no idea, they sure did not use SAE on the tow ratings except for the 450. That's why I am asking.

GM is very clear about SAE Flywheel horsepower. Seems they always did well with "less power".

Ford uses SAE J1349 and I also believe GM does as well. They have been using that standard for some time. What standard does Ram use?

Ford is using SAE for towing for 2017. The ratings basically stayed the same or increased from the non SAE ratings. With Ram using it they still put in fine print that the weight ratings are an estimate only. If you want to hang your hat on these ratings, fill your boots.

since 1972 federal laws have required horsepower claims to be SAE Net horsepower. That is power with ALL factory stuff hooked up and operating, factory fuel delivery etc. and horsepower measured at the flywheel.

The old SAE gross hp was just that gross. Mfg would add headers, remove air cleaners, disconnect alternator, water pump etc.

The other option mfg have is SAE certified where there is more certification and testing required to a very specific standard test method, but IMHO the difference between the certified and SAE net is probably not something most of us would be able to notice.

I believe GM uses the SAE certified hp for the duramax.

Question, is the PowerStroke SAE "Flywheel" rated horsepower?

Nice to see GM went with a more dependable injection pump.

My understanding is they upped the power substantially. HP is a little higher than the Ford and torque is about 5 pounds less. Overall, a substantial increase from prior years.

Did GM up the Diesel power or not.??Some reports say the same as last year,somewhat disappointing if they only added forced air induction,Whoopee Do.

Yes especially the 05-07 models that are not beat to a pulp. My BIL flew to Arizona to purchase a 07 5.9 Dodge because everything around here was just beat up and still asking for crazy prices. We purchased a 05 5.9 Dodge and a 03 Super Duty 7.3 just by a phone call from my cousin that's been on watch for any good trade ins at the dealer he works at. You have to move quick or these trucks get sucked up.
