I don't know Supras but if it has a MAF sensor before the turbo you will not get any BOV to sound good as the outlet of it will have to be plumbed back to a T fitting between the MAF and turbo inlet. If you leave the BOV outlet open for good sound the MAF will sense the airflow and the PCM will add fuel which will flood the engine or at least make it run rich for a few seconds after each shift.
