Those that have tuned or programmed

SCT tuner on Ford 7.3 diesel. Now it is a hot rod. I only tow in tow mode.
Record mpg empty is 23.8.

FWIW, I enjoyed it and learned a lot. Thanks for starting the thread.

Well, once the testosterone taps get turned on, it can be tough to turn 'em back off.

No kidding!

Sorry, I will stop. My goal was to provide some kind of info on what your truck can sustain at certain tuned power ratings, and what mods are needed.

There is nothing wrong with advertising short burst power over sustained power. It is completely legit using SAE methods and all of them do it to a certain extent. Some more than others. To some companies, highest power ratings possible is more important for marketing and being "best in class". Other companies feel that sustained power is a more important figure for their customers. I have worked for both Ford and Cummins and I would definitely put Ford in the former while Cummins was more in the later.

Ford knows that "best in class" power ratings sells more trucks, and they will do whatever they can to keep these titles. So does Ram, and they(or Dodge at that time) wanted Cummins to post highest power levels possible back when I was there and probably still do. However, that is not the way Cummins does things and would rather give a more sustained hp rating to their customers rather than a short burst power rating so they tune their engines accordingly.

Take the Ford F450-550 and Ram 4500-5500 trucks. The highest rating for the PSD is 330 hp while the highest rating for the CTD is 360 hp. That alone tells you that the Cummins is able put out more sustained power since the emissions and power certifications on these trucks is geared towards the emissions and power at sustained power outputs.

Oh ya the Powerstroke is rated for short bursts. Is it the intercooler that can’t keep up? Them dumb engineers made all those changes to the engine when all they had to do was increase the size of the secondary radiator. ;)

More passive aggressiveness. I thought we already covered the difference between short burst rated power outputs and sustained rated power outputs and how sustained power is more important while towing.

Although it is not just about power, it is also about fuel economy. Tuned, I am able to pull up hills at lower rpms that would make my father in laws 2019 F350 downshift into a lower gear at much higher rpms. It takes a lot to make it shift out of the 1,800 rpm range at 65 since I have about 400 hp available at that rpm.

I guess I don’t pay enough attention to the tune threads as I actually didn’t know you had a custom built 68rfe .... I think that is a good move for those who like to push their engines power levels. I will be replacing my truck soon and although I’m leaning toward another Ford I might even take a Ram for a test drive ... I do like the Ram interior. If I buy a Ram I certainly won’t feel a need to modify it as being third place in the power war would not be an issue for me.
