Saying which one to look at more than the other is rather moot. SAE seems to be the standard practice, but as long as you comparing same correcting factors between dynos, that at least removes some variable. Some people prefer STD, some prefer SAE.
Thanks! I guessed as much but wanted to make sure what it really was. I always look all data given anyway
