Why would that fix KRKTE if you set it wrong for your injectors?

This can't be done w/o getting your MAF scaling right as well. In general, you start with KRKTE at theoretical, TVUB from injector specs, and scale the MAF until your trims are right (assuming you have no idea what your MAF curve is.)

If you do know what the MAF scaling is, and you leave it at theoretical, and your trims are WRONG there is something wrong with your assumptions.

Find out FOR SURE what your MAF diameter is compared to the file you intend to use. Don't guess.

Same with the MAF sensor.

I'm really puzzled as to your approach here. None of what you posted really makes any sense to me.

I think it would be better to start with a stock file for a ko4 and go from there. I know from working on these cars ( I'm a mechanic / tech over 10 years) that the tt 225 uses same diameter housing as 2.8 12v/24v now the sensor is from early 12v is the same but halfway thru 12v they changed it and that carried over to the 24v. This is more or less a test to see if the car can boost properly with a factory K04 tune and hopefully it will be less intensive on the tuning side....

Dude stop, listen if you want to use a bigger maf thats fine. Pick a maf use the maf tables from that ecu in the file your tuning.
Stock maf should be ok for K04. I think you should start over to be honest stock file adjust for your injectors add fuel in the way you
choose, pull some timing out, add boost till you get what you want then add timing till it pulls 2 or 3 degrees done.

Clearly its not really this easy but you are making it harder by mix and matching parts.
If you max your maf just go to a s4 bosch super easy to get maf tables for.

Can I just ask why you're using an early sensor on a late car?  I think your sensor isn't correct for the management. 

Run a VR6 housing but the stock AUM/wideband sensor.

ok so im abandoning the 06a906032dl file and using the tt file 8no906018bb

As others have already said, your approach is wrong here.   You are destined for failure using a TT file on a AWP.  As far as I know, there are hardware differences (like an EGT sensor).

Start with a damned AWP file and properly calibrate your MAF maps based on a KNOWN good maf/housing combination (s4 hitachi or bosch would work fine, you can copy MLHFM/MLOFS directly from stock files).

Moving to a non-AWP does not help you in the least; it does NOT mean you have to learn less or tune less.

The opposite is true.

Not only are you insisting on taking short cuts out of laziness, they aren't even short cuts to begin with.

This is getting frustrating because you're just ignoring everything everyone is telling you and going off on some other bizarro digression.

For k04 tunes, I just use a larger MAF housing with the stock sensor.  Works perfect.

There's even a "mafadjust" program on here.  Simply give the program your bin, your current housing size, the new housing size and IT DOES IT FOR YOU!   Couldn't be easier.

06a906032hn file check, and stock maf check. Log, go from there.  Eliminate any other variables this way

Um stock file with fueling changes for the big injectors?
Maybe pull some timing aswell, I mean the ecu will pull it for you but the point is to do this right.

Finally got rid of my throttle cut issue. I had to raise the values over boost threshold and now I have wot all the way to red line.

My fueling is good, spiking 25 holding 15 to redline. I need to work on the timing but car runs strong.

The when running near or over map limit there is a threshold between requested and actual. That value needs to be rasied. In my case I don't have the time to do the right thing like a 1320 hack. This works well enough for me and my needs.http://nefariousmotorsports.com/forum/index.php?topic=114.0
