I’m not much into dyno numbers.

Well, It's not about telling the dyno operator to lie. That's not what I meant. What I mean is, one dyno can say one thing and another something completely different, so those numbers are really irrelevant. With dyno sheets, all you have are pieces of paper. It's sorta like when someone issues a protective order. As they say, "they aren't worth the paper they're written on". The dyno info is only half the picture. The drag strip is the other half. Without the drag strip, all you have is a piece of (expensive) paper.
If you've been around badass engines enough you can tell if it's badass or just irrelevant pieces of paper. You might be right if there's factors involved like elevation but if the correction factors are identical between 2 dynos the numbers will not be far off. I don't disagree with you about the drag strip . I'm lucky I don't have to pay for dyno time. But if I did after what I know then I would gladly pay to know where my engine is at it's happiest and not having to guess on gears and converter
