STD is less comparable across different temps and humidity than SAE. It bugs me when tuners post numbers with STD rather than SAE because either 1) they know it shows bigger numbers meaning they are trying to decieve you or 2) they dont know any better. Either 1 or 2 is bad, if its a dealer tune its likely to be #2.I like the torque is right there out of the gate. With all the reading I do I see that STD instead of SAE smoothing was used. Now while I have no freaking clue of the difference, from what I've read posted by engine builders, there's a slight difference in overall numbers. But then again, you can't ride a piece of paper. As long as it runs good and you're happy with it, that's all that matters.
