Golf 4 AGR tunning

I had spent so much time to understood this ecu that now I can manualy find maps in text mode with winols :D There is so much maps but many of them are empty to find them I had found pattern to look for and hope someone will find it usefull:D
Lets begin:D
So switch to 16-bit mode and decimal format in winols, now try to find 45000+ nummber foloved for example by 00010 but this nummber can change from 1 to 50 at least I havent found larger one, so what this will mean - the first largest nummber will be x axis signature for example 57482 will be engine speed signature followed by 16 that will dterminate 16 clumns of table and after this you should find 16 nummbers that represent diferent engine speeds after this all you should be able to see next large nummber in this case 56624 that is injected quantity signature folowed by 13 that will determinate 13 diferent injected quantities. So for now tou should be left with something like this:

57482 16 0 798 819 903 924 1239 1386 1491 1596 1743 1995 2247 2499 3423 3612 5355
56624 13 0 300 740 1000 1240 1500 1740 2000 2240 2500 2900 3300 5100

and after this you will find map data 16 x 13 = 208 data fileds representing map in this case this is egr map. But remember there is maps that only contains one axis folowed by data for example signature, x axis field count, x axis description and data itself.

P.S signature nummber usualy is from 45000 to 60000 and ther is some list of signatures that you can try to find and they most likely will start map.

49154 c002 Temperature C ?
49156 c004
49156 c130 Temperature C ?
49178
49624 c1d8 Throtle position %
49652 c1f4
49764 c264 Atmospheric presure Bar ?
49842 c2b2 Atmospheric presure Bar ?
49854 c2be Atmospheric presure Bar ?
49978 c33a
50000 1388
50004 c354 IQ mg/str ?
56342 dc16 Boost presure Bar
56470 dc96
56624 dd30 IQ mg/str
56646 dd46
57052 DEDC IQ mg/str ?
57120
57160
57162
57192
57380
57482 e08a Engine speed rpm
64566 fc36 maybe signature :D

And now I would be happy if someone out there would look to my "tuned" file and say some critics of my work whats wrong and what horibly wrong as this is my firs attempt to all this. And if someone could explain how to tune boost Target it would be awesome:D as what I did was basicaly looked at some examples and tryed to recrate them. My turbo is kkk k03-015bb5006748.
And also what should I need to log with vcds during tunning this ecu?
