I am with you on having a extra spring for safety. But Beehives are used as factory equipement on many engines, including all LS engines.

Two springs equals twice as many things to break!!!

FWIW I used beehives and my engine revs to my limiter of 6800 no problem...IMHO beehives represent state of the art in valve train technology and to the best of knowledge have proven to be highly reliable

..but back to your concerns, looks like your MAP is at 99.8 at 5863 rpm......just curious do you have a MAP logged from this same run at a lower rpm??? ..going way back to your not enough air posts, which I am not sue if you ever resolved or not..
