The blitz BOV has been known to cause idleing issues on subarus.
Not on all subarus - had my car 13 months now had a baileys on at first,caused erratic idling whether car was hot or cold. Then tried a forge dump valve,pretty much the same as the baileys,but not as bad.Finally fitted a blitz and up to now no running issues at all,yet there are people who have baileys& forge dv's fitted and report no problems at all.
Having my car mapped after xmas and the mapper has no problem with the blitz bov being fitted saying it is 1 of the better bov's out there.
If i do find that the blitz does cause any running issues then i will definetley be sticking with the standard recirc valve,which i believe is good for up to 350+bhp.
