Thanks guys
see the last log i posted, after i plugged the MAF and run pure water in the meth kit the retardation was much better.
i have ordered some meth and i am waiting for it to arrive so i can further test the timing problems.
i may have know whats causing this max retard of the timing. for some odd reason the engine fail to check the o2 sensor and i got this in vagcom (see the attached image) but after i re-flash it will "Passed" and the engine timing will be much better.
should i go and change both o2 sensors ? or leave them ?
Another question: whats the name of the map that control the timing passed on the AIT ? so i can tell the maestro guys to add it.

Sure thing.
But is it really broken or the ECU is malfunctioning? since sometimes it works just fine
