To answer my own question about disabling BTS: the method in my post on the last page works, BUT LAMFA (or other method of requesting lambda) needs careful tuning especially in mid-high RPMs, part throttle to keep EGT down. EGT under WOT without BTS is not a problem if your last LAMFA row is sensible. I tested several runs to redline in 5th with EGT staying under 1700 Fahrenheit. Unfortunately not able to tap out 6th due to traffic but I suspect similar results since my EGT actually begins falling after about 5800 RPM due to slight additional enrichment I've programmed.
My load limit issue still exists and it looks like I'm being restricted to about 85% of my LDRXN curve at all WOT specified loads of 185-190+. It's not an IAT, EGT, or boost regulation / deviation issue. Who would like to guess the most likely culprit while I hunt it down?

I've been having that issue too, and I've just been living with it since I couldn't seem to find anyone else with it. I just figured that's how it is! plus I only have intake and 3" downpipe, so I'm not trying to squeeze everything out of it yet, so its not super annoying yet

LDPBN and KFLDHBN raised up enough that they arent interfering? Or maybe they arent high enough for it to reach your req load?

I'll have too look to make 100% sure but I think those were the first things checked, for me at least |

I don't know how kflbts became a potential culprit in restricting load requests. It's made for component protection enrichment.
If ldpbn and kfldhbn are checked off, there's no issues with the irl/iop relationship then the next likely culprit is kflmdmx (sp?). It may be restricting total airflow.

Are you referring to the wastegate duty limit map? I'll scrutinize it after testing / ruling out some load-request changes suggested by smelly240.
Here is a full list of all hardware changes to my 2007 BPY FSI 6MT 1K0907115H that may be nonstandard, just in case:
--No MAF sensor (nothing done in software)
--RFD with motor removed, disconnected (nothing done in software)
--Rear, post-cat O2 physically removed (some software mods for emissions but still throws open circuit fault for the heater)
--BOV (does not cause any error codes due to MAF removal)
--Vent to air PCV
--Total evap removal
--ESP inertial sensor removed to perma-disable ESP / TCS
--Airbag module removed

It's not boost control, it's KFMLDMX. It's a diagnostic limit for airflow. |

I maxed the entire table for KFMLDMX @ 3200 KG/H which is nearly 1,000 g/s airflow. MAF reading in VCDS is 300-something with MAF unplugged.
Testing shortly.

Never max KFMLDMX. It's signed...... |

I just put mine up to where I know is just out of reach.

I did originally FFFF and wound up with a small negative number, lol. Then entered 3,600 in the scaled value box and found 3,200 is the max positive value KFMLDMX will accept. Anyway, drove the car around with the modified KFMLDMX and it is running smoothly with EGT back to quite reasonable levels as BTS is also re-enabled, and edited for more reasonable mixtures at high load. Unfortunately, the boost restriction remains. Same boost profile as before, with about 17-18 psi max and <10psi after 6K. Also revised LDRXN and IOP / IRL according to advice from smelly240, and those revisions had no effect either. LDPBN is set at 2.5 bar all the way above 3K and KFLDHBN is set 2.5 bar up to 60*C intake temperature. I always include intake air temp in logs if there's room and it's usually been below 45*C in this cool weather. |

iirc isn't one of those the pressure ratio?? |

7fff is the largest 16bit signed value.
