I wonder if this could be fuel injector related? As in, there's sufficient fuel being sent from the pink, but the injector(s) isn't opening at the correct time? Is that a thing?

In case anyone's still listening, here are two back to back logs. The first was at 17psi and had (essentially) NO stutter issues. The second was at 21psi had immediately started stuttering/running rough starting at around 5K and 5.5K RPMs. It stayed rough through the remainder of the pull.

AFR and Boost are solid for both pulls so you'd really think it's spark related.
