off the top of my head, you should be looking to pull 1 degree of timing for every psi that you add. so tune off boost for max drivablity, then just remove 1 psi for every 14 kpa you have on the left of your table.

Nick, that's exactly what I've done right from the beginning, except that I retard 1 deg for 0.1 bars which is very close to what you said. Problem was in the ignition settings (inverted/not inverted). Now the car is awesome to drive, very smooth and lots of power. Good point about the spike, can you post the map when you get a chance to use your memory stick ?
P.S. The above map was just to get the car running well after experimenting with various ignitor settings.
