There is a certification program that ensure that claimed Horsepower and Torque are what they say they are.... at least as specified by the test.
http://www.sae.org/certifiedpower/
Quote: Power and torque certification provide a means for a manufacturer to assure a customer that the engine they purchase delivers the advertised performance. This SAE Standard has been written to provide manufacturers with a method of certifying the power of engines to SAE J1349 or SAE J1995. Document SAE J2723 specifies the procedure to be used for a manufacturer to certify the net power and torque rating of a production engine according to SAE J1349 or the gross engine power of a production engine according to SAE J1995. Manufacturers who advertise their engine power and torque ratings as Certified to SAE J1349 or SAE J1995 shall follow this procedure. Certification of engine power and torque to SAE J1349 or SAE J1995 is voluntary, however, this power certification process is mandatory for those advertising power ratings as "Certified to SAE J1349".
Now the big question:
Who, Dodge-Cummins, Ford, GM, Chrysler, etc. went to the trouble of certifying their motors commonly used for towing?
At $1,000.00 each for every copy of the level 2 tests I'll leave posting that data up to you. But if you are taking orders, I'd like to see the data on the GM LML, LS7, and if funds allow, the L96.

Thanks in advance.
I am going to see if I can get some of the data for you.
Seeing the raw data cost money, but GM is entitled to put "SAE Certified" on their HP and Torque claims.
It is a voluntary standard. The power of the standard is in watching who certifies what and who goes out of their way not to certify their product.
I can understand if Toyota is not terribly interested in certifying the low end Corolla.
It gets harder to understand when a product sold on its horsepower and torque is not certified.

The only thing that matters to me is does my TV have the hp &the torque to get me and my trailer up the next hill. I'll be sure to blow the horn & wave as I pass you on the next hill.

I never fail, I just succeed in finding out what doesn't work
SAE certification is really expensive. I don't remember all of the details, but to claim SAE certification the dyno runs are done in an extremely controlled environment, under very closely controlled conditions.
The SAE also requires that their technicians are present to witness the dyno runs.
This isn't new to GM. They have been doing this for many years. It would be good to see more manufacturers jump on board to give an honest comparison for similar models.
Interesting that GM, of all companies, is taking the lead in many areas.
They are a leader in towing certification, horsepower certification, etc.
I have never been impressed by the scamming that is done by marketing departments, and more and more, I am getting to like GM even though I believe that their business model makes for higher priced lifecycle cost of ownership.
Did anyone notice that Chrysler and Cummins engined models are not on the SAE certified lists? They have for years made claims that they have certified them theirself as the SAE Certification criteria is not friendly to their engines/etc. Same with the new 2013 towing guides as they claim their rating systems are better. Ya right! The caviot should read that "we can't match up to the competition and don't want the truth out". My business worked with Chrysler Corp and their vendors for several decades a know their ways and games they play. Why is the buying public so blind? Nuff said!

Right on!
What is important is not the paper specs, but whether you are happy with the package and it does what you care about for what you want to pay.
Then there are ones of us who want to pay lots to show others we can and by extension, the others can't.
So much of owning toys is fulfilling emotional, and not technical needs.

Notable absents include the F-150 Ecoboost.
Now, I understand they didn't want to certificate it right away, because they were probably doing a lot of tweaks and each time a tweak is done, it needs to be re-certificated.
Having said that...
They did certificate Ecoboost on two other models.
I do note that there is no excuse for not certificating the Ford 6.7 Diesel.
Someone inside the bowels of Ford know what the SAE Certified output of the 6.7 diesel really is.
In the absence of information, it is reasonable to say it is below 400/800.
