Sounds to me like your map is asking for loads of boost, add that to the fact you dont really have a tried and tested FMIC and standard downpipe and cat and your gonna get some problems.
sorry mate but i ran this fmic for over a year as did turboboy so i would call that tested never once did we have any probs and as for the downpipe turboboy ran the same set up as me but with a standard downpipe where as i had a miltek and we both made the same power and torque from jabba.
flash had the boost controller taken off today daz from jbs done a little write up for you mate to put back on the car
