The J2723 that GM uses still uses either J1995 or J1349 as their dyno standard, but has an extra validation step.
What is the extra step?
Just an extra certification process that consist of giving SAE more money to have an SAE certified witness. Basically, you are paying SAE more for the right to say it is "Certified to SAE J1349” or “Certified to SAE J1995."

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.
