Having an SAE witness to the testing IS important. It means that there will be no funny buisiness in the testing.
Not having the witness means that they are basically self testing.

My company has many processes that they self validate monthly. Every 6 months or so a higher level of management comes in and does the validation... The previous months high scores always shrink a lot. Some of our more critical processes entail a outside 3rd party coming in to do the validation.... That is when you really see a true score.
I liken this to what SAE does when it witnesses a test.

It is human nature to want a good score.... And when the fox is watching the henhouse, that is what will happen.

And that is why some manufacturers have come up short so often in the IKE tests, despite having higher power numbers.

I really don't care if they have a witness or not. Probably because I don't care too much about stock power numbers since there is a 99.99999% chance that I will dyno and tune the vehicle myself within the first 10-20k miles of ownership.

Having personally witnessed these test myself at Cummins, I am worried about them fudging the numbers just to get the highest horsepower numbers. I can't speak for Ford. Not saying they do or don't, just that I have never seen it with my own eyes.

In regards to the ike test, that is what we are discussing here. Ford may very well have more short burst horsepower than the Duramax and Cummins, but may not be able to sustain that power for as long of time. There is a huge difference between the power an engine can make on a single short burst dyno run versus an eight mile up hill under high load. After all, with a 60 hp advantage, the Duramax should have mopped the floor with the Cummins on the last supper Ike test instead of being less than a 15 second difference.
