Dealership Frauded Us

I pulled 140,000 lbs super b trains through the Canadian Rockies, prairies, Ontario and Quebec with a 450 hp 1,550 tq Mercedes.
Yes it was a dog, but it did good on fuel.
Some modern engines (Detroit’s) are sluggish when new, but the ecms are programmed to operate at reduced power during a break in period, then get to full power closer to 80,000 miles.
Not sure about the Cummins.

 

It could since it's a new truck. Maybe wait till it out of warranty for more power.

 

500 vs 565 doubtful any "butt" dyno would be able to feel any difference. Edit Why would the boss order the X15 Efficiency Series?

Frauded is just funny

 

Sticker on his engine says 1850 ft-lbs torque at 950 RPM. 500 HP at 1700 RPM. Engine is governed to 1700 RPM

 

The new fuel-efficient ratings build upon the class-leading low-end torque that is readily available at 1,000 rpm. Customers who traditionally opted for a 485 hp or 500 hp rating to access 1,850 lbs.-ft. of torque can now benefit from the superior fuel economy of operating at a lower rpm while satisfying performance expectations.
Customers that typically operate in high-load conditions (gross combined vehicle weight over 80,000 lbs.) or in mountainous terrains, and want to achieve better fuel economy should consider the 1,850 lbs.-ft. torque ratings.

 

Torque moves weight, not HP.

 

It doesn't really matter as my productivity series X15 is governed to 2000 RPM but makes peak HP at right around 1500 and never goes up from there. I also own a 600 HP Signature, a 565 CM870.. and this 500 X-15 does just fine. I haul loads up to 88K with mine and it is a great powerplant.

 

"Tweak" is absolutely possible at the dealership (legal) level. If you have them bump that 1700 to 2100 you will get what you are looking for.
