This means something else is VERY wrong with your setup.

Indeed.  There's an undescribed map for max IDC/NMOT =  limit of IDC when the controller isn't turned off (duh why), worth logging all of the vars, checking fuel pressure as above, and maybe flow test injectors....

OP keep an eye on your plugs!

I thought about checking fuel pressure. Not sure how one would do that tbh. Plumb a gauge post fpr?

And keep an eye on my plugs? Meaning spark plugs? I checked gap recently, they were way out. .032. Should be .028-.025. Gapped them, no difference. I tell you, i replaced the fuel filter not 10,000 miles ago, unless someone poured sand in my gas tank, thats not it.

Yes, indeed there is something very wrong with my setup and thats what im trying desperately to find out cuz everything fueling is stock including maps (minus changes i made to tlafa, lamfa and tabgbts)

I clear codes in instruments and airbag everytime i log cuz i use me7logger and i have a mk4 and have to pull my instrument fuse every time i log. I check engine codes when i do this to monitor things.

Got two new codes. One of which keeps appearing and dissapearinng once in a blue moon.
16891/P0507/001287 - Idle Control System RPM: Higher than Expected.
and
16885/P0501/001281 - Vehicle Speed Sensor (G22): Implausible Signal (Keeps appearing)
 The odd throttle behavior in my logs makes me suspect theres something to p0507 and the cold start issues i have.

Also, ive been noticing a pattern:
When i flash a new bin and go out to log, i do a wot pull and when i let off the gas pedal completely (and every subsequent gear used after wot for aprox 5-10 mins of driving) the torque drops out hard, like as if im hitting a brick wall. Its a sudden jerk of deceleration that does not occur before wot. Something to do with fuel trims?

The P051 might not be helping.  Yes spark plugs I meant.  It's RKTI I bet log the vars responsible for torque cap/reduction....It's in the wiki in English

If you are hitting BTS and enriching past 100 IDC, may as well numb BTS to 11.5 and call it a day, because it won't do you any good w/o bigger injectors.

Also, this is what im interpretting that everyone wants me to do. Im fine with that. Question is how becausr i keep numbing bts but it isnt responding.

Im gonna need some elaboration. RKTI? VARS?

Changing the BTS EGT thresh isn't really completely numbing it.

FR module RKTI is responsible for KRKTE etc.  It has a torque limiter that is used in load reduction in another function.

VARS = variable in RAM where the RKTI vars for torque pid reduction is stored.  MITIBGR_W for example.  Read and you should understand what I mean.

If the injectors are big enought then maybe orings, maybe erm FP as said.  Lower boost until you fix it IMO

Sounds like you have several issues perhaps but fixing maxed injectors would be at the top of my list.

Maybe you should go back a step and read about turbo engines and FR/wiki here.

BTS forget just now.

I'm still wondering why he's hitting 100 DC so easily. Not that familiar with the stock 1.8t injectors... can they really not do 11psi at 11.5 AFR?

Lets get the part numbers and run the math?

Edit looked quickly and @ 3 bar it looks like they are 90% stock

I'd think if it was that far off he'd throw a lean code... should check his ltfts.

Good point, I can see any mention of injectors for a remap googling so H/W I'd lean to.

Done it again it's late lol
