I just took a quick look at the logs. Do you think it might be commanding too much fuel, causing the HPFP to crash? It seems like the AFR goes rich at the exact moment the HPFP pressure starts to dip. I don't know why the tune would be doing that, but that is sure what it looks like.
OP - You seem to be missing a lot of parameters. I think you need to do more logs with, at a minimum, lambda target afr added in. Then we can see for sure if for some reason the target AFR dips, causing it to go rich and the HPFP crash, or if it just goes rich without a target AFR drop.
