Just around 4k: Note: actual boost is right at the map limit, not over. Tried tweaking FKKVS, and KFKHFM. MAF isn't underscaled, it's an RS4 unit running RS4 MLHFM.   |

Perhaps the pump isn't maintaining pressure at max boost? Got a FP gauge?  |

No, but that's sorta what I was thinking as well. Pump just can't keep up.
0 misfires.

How would a pump be unable to keep up at 4k then be fine as rpms rise? Fuel pressure regulator maybe, not closing with boost properly to increase fast enogh.
How about vvt change over? Is that tuned to activate/deactivate at that rpm?

This was my first thought when I saw the area where the issue is. |

Looks identical with VVT disabled as well. |

I'm sure it is something I'm doing wrong, but I use the same base and have never had an issue before. Worth noting, I'm not charging anything to do this, it's a friend of a friend. |
