No idea...
That's the turbo I have:

KKK 5304 101 50 63
As You can see, it has been rebuilt with some better performance parts. Standard turbo blew only 0,3 bar.
Tweaking the fuel pump maxed the pressure of this (renewed) turbocharger up to 0,7 bar. Tweaking it even more didn't do any further improvement, just black smoke.
