Are you venting the BOV to atmosphere?

He wants to know if you have your BOV recirculated or is it venting to atmosphere (show off valve)

Is it stock BOV? If not what do you have?

it is a tial bov and its venting to the atmosphere

that is your problem you must account for the bov in your tune or recirculate it if you recirculate it no adjustments need to be made with you tune but you surely can fix it with you power fc wait power fc right i never heard of super fc but either way yeah you can problem is you can recirc a tial your have to vent to atmosphere the easiest fix for this is put a stiff spring in the bov because it sounds ike it open at idle and thats your issue that should fix it..

this is how hard it is to read your jibberish. use grammer and punctuation.. seriously.
