i tried to sort a definition for the same box, but it was very time-consuming to get it running, esp in the beginning when i had no clue as to what maps i needed. (its 1000 times easier when you know exactly what you are looking for).
so as i was going to do a K04-upgrade at the same time, i ended up flashing this TT-file into the box, 8N0906018F, which it accepted 110%.. the definitions for this tt-box is available allmost fully defined.
im sure you could input maf, injector and k03 pid/ldr-values into this k04 tune and get it running 100% as a hybrid tune.

not saying you should do this, just pointing out that it worked wonders for me on that particular car ~1.5 years back when i knew nothing of this.

today I have tryed TT file on my car and it start fine but I got some errors, secondary air injection and air bag control, first I can disable from file but air bag control?
