^ yup...

most race cars and rally cars do not use anything. crawford performance has made multiple statements on here as well as iwsti about there not being many if any negative effects to running without one, and they stated that they delete the bpv/bov on all of their race or rally cars.

the only way you could possibly tune for it would be to switch to speed density or blow through.
