vanos problems

Hi i am getting ready to dyno tune my e46 m3 that has been converted to turbo and i am having problems tuning vanos. The problem is by default on the infinity the vanos load is set to TPS VS RPM. Now when i try MAP VS RPM it will not read over 100kpa so i left it as it is provided in your base map. this is the first time i am tuning anything vanos related and i don't know if the load for vanos should be tps vs rpm or map vs rpm now that the car is turbo? 

Another thing to note is when the car is cold it pulls hard and works excellent but once it has gotten to working temperature it somtimes pulls hard but it somtimes pulls slow as hell. Now i have logged the data and looking at vanos shows me all these fluctuations, let's say on vvc1 the cell might be hiting target 21deg advance but in the log it's showing me that it's actually giving 30deg advance or 15deg advance thats why in the log vanos keeps fluctuating i know this has to do with vvc base duty and feedback and the settings it has there. I have no idea how to setup vvc base duty and how it works i have tried finding it in the infinity manual but it doesn't explain it. What am i doing wrong?I know i should have tuned it first with vanos off then tune vanos on the dyno.The car is tuned for max 1bar now.I want to figure out this problem before taking it to the dyno.

If you guys can please have a look at my logs and tell me what i am doing wrong that would really help me!
