hey, nice to see your progress. got a few questions for ya though..
what are you using for tuning?
your car runs a MAF sensor instead of MAP and you are currently running your MAF sensor in BLOW THROUGH mode.. although this is good sinc you dont have to recirculate your BOV so your car doesnt spike fuel every time you let off the gas.. its bad because the stock MAF sensors aewre not designed to SEE any boost. thus any boost will cause your MAF sensor to max out really quick most likely causing bucking, hesitation and unreliable fuel delivery.
most people with MAF sensors run their MAF sensor in DRAW THROUGH where the MAF sensor is placed PRE turbo..
example AIR FILTER>MAF SENSOR>TURBO INLET of course when you run it in this method you MUST recircluate your BOV so that you dont loose any metered air.
if you notice almost all factory turbo charged cars with MAF sensors are running this method.. DSM, Supras, Skylines etc..
so back to my question.. what are you using for tuning?
