Hello trying to decide what i should do at this point. I just recently installed a tmic on my 2011 wrx. Im running a protune at 20lbs boost and since ive put the tmic on i have been hearing a flutter from the car which people relate to compressor surge. im boosting to 20-21 lbs and dont seem to have leaks or anything disconnected. Seems the last part is the stock BPV, should i upgrade this since it seems it would help to control this. Im going to go a full recirc bov not VTA. Any advise would be helpful.
