I dont get what you are doing here. You see what your turbo can do. Why did you just reduce the whole thing instead of leaving the low end where it was, and tapering up top?
What is was your rationale?
I miss under stood, I hoped lowering LDRXN Would Level out around 6k. Can you explain leaving the low end and tapering up top? |

LDRXN as you can see it go tru RPM range. Your boost meet req at low RPM (3000-4500) so you don't touch these. That is low end RPM
Question for everybody, why after 5200 RPM lambda control stop working? I have identical issue on my B6 8E0909 AH file

Why are you lowering LDRXN at low rpms the same as high RPMs when it is quite clear your turbos aren't behaving that way. |

Because I misunderstood "drastically pull back your req boost" I thought that was in reference to all of LDRXN. I Undid the changes to lower rpm range and pulled back the upper rpm range.
HWNumber = 0261206890 (requested was 0261206890)
SWNumber = 1037363351 (requested was 1037363351)
PartNumber = 06A906032DL (requested was 06A906032DL)
SWVersion = 0004 (requested was 0004)
EngineId = 1.8L R4/5VT (requested was 1.8L R4/5VT)
VAGHWNumber =
ModelId = G

Get rid of that gigantic cliff at the end, you don't want huge changes in req boost, nor do you need that huge dropoff
Once you have req boost where you want, the next step is imx

I cant seem to iron out the changes to the high rpm in ldrxn. Im shooting for 10 psi but i keep boost keeps fluctuating.

Your req boost now makes even less sense
It's so wrong the ECU is closing throttle, because your PID is numbed out.

more or less follow this for taper, but stay a bit under it after 4500RPM

Looks to me like bad IOP/IRL |

I adjusted LDRXN like you said and also increased IRL slightly. I left IOP alone because the last row is at 95. |

You're out of injector, you may want to pull a bit more boost after 5400 rpm

You miss something, injectors have enough flow for that boost, fueling is set bad. Injectors are not dialed in
