People often forget that these tuners all have to try to keep correction factors for fuels used, environmental differences, etc. in line all the time. The tools are good for seeing gains from mods but not for judging the engine's "actual output". The SAE tests are done in a much more controlled environment and are much more useful when used in comparisons between vehicles.

I agree with you. I just find it odd when these guys are guessing the baseline whp before adding mods / doing first pull, they are always guessing 420 to 450. That's a lot more than 455 crank.
I'm always in disbelief at the numbers they're throwing out there for guesses, then they do the pull and
They must be doing some baseline tuning to help get those numbers up and its not shown on video.
