Is it always Cyl 1 and 5? Moving around would make me thing fueling issue. If its always 1 and 5 it'd likely be something cylinder specific like injectors.

Can you post a log?

Not sure I agree. Had an issue with my HPFP and had misfires on 3 and 4 only. I even changed the injectors for those specific cylinders and misfires continued.

Logs will certainly help Isolate the issue.

That's actually pretty interesting. HPFP dropping pressure at a specific interval like it's not supplying enough at intake stroke for 3&4...

Multiple cylinder misfire is typically a bad HPFP
