How can I find out how many horsepower my engine is?

What is the last six digits of your VIN? I could look up what partspro shows for your horsepower and torque.

 

I wouldn't go plugging a laptop into a company truck. You might get fired for that. Besides, they probably have a password set on it.

The DD15's that say 505 HP are usually switchable between 505 and somewhere around 465. Why are you worried about that anyway? If you're not having to pay for the fuel then the thing to covet is a taller rear gear. The 3.43's pull hills better than the 3.25's.

 

Rear end gear.
Yes.

 

I’m beginning to smell a troll.
If not, I suggest reading a book on the basics of mechanical operations.

 

Having cruise speed higher than foot pedal is by far the stupidest thing bean counters do.. it encourages cruise use at the worst times to be using cruise . It also causes elephant races when truck catches another .

 

Yes.
