All engines must have identical design properties in your world. Why doesn't my Miata make power at 14,000 rpm reliably like my motorcycle did? Surely they are both engines! Maybe I am just a fool for not trying to rev my Miata so high. I haven't tried it and it just might work.
I'm going to recommend you do some reading on internal combustion engine design and theory of operation before making recommendations to the other noobs. Study things like rod ratio, undersquare versus oversquare engine designs, quench, tumble and swirl, combustion chamber design, the effects of cam duration and overlap on dynamic compression ratio, and definitely forced induction detonation characteristics relating to mechanical compression ratios. Report back your findings for us.

I started with automotive textbooks for theory of operation of all components and then transitioned into performance enhancing technologies like combustion chamber design, camshaft design (including all of the "Camshaft 101" lessons from major camshaft manufacturers), intake runner tuning, and all of the other terms mentioned in my other post. Then I transitioned into forced induction theory and operation. I would recommend the book when you reach that point, but not before then. Ideas build on each other.
I've been at it for awhile but still have a lot to learn. Technology and understanding keep progressing. But our little engines were designed in the 1980's using technology that was old and not cutting edge at that time. Mazda is small and quite poor compared to Honda, Toyota, and Nissan. They used existing architecture out of necessity.

Here i am quoting myself in the hopes that i will be able to see my reply so i can read the rest of the thread.
@Robb M. it's happening again.

Our tech guys were unable to replicate, I haven't yet either. It's def not your machine based on the above. Not even sure what info I could ask you to try and collect to help isolate this. All I can think is a rogue ad unit. I'm certain you have related threads and infinite scroll turned off?
