or be a fully sickunt like me and don't run a
bov at all
turbine flutter is bliss (sound wise, but terrible for your turbo - i reckon
). and i don't think you can get yellowed for not having one. but my flutter is ridiculously loud - infact it's more an amplified dose than anything. come to think of it, i'd probably get yellowed if i let it off on fullboost due to the sheer sound of the thing..
simple fix: whack a stockie on whilst taking it over the pits, then remount your ssq after it's been passed - and from there on in; drive under boost around busy areas/cop hot spots (that's what i do), or, alternatively - get a plumbback. atmosphere vents sound ricey as fuck imho.
