ATMOSPHERE:
-- Use full-size vent piece
-- Make sure both springs are in the BOV (comes already like this when bought)
-- Tighten the BOV adjusting screw down to about halfway or a bit more
-- Loosen more if you're getting surge above 1-2 PSI of throttle release
-- Tighten more if it's making a long bird-singing noise after releasing or if your vacuum reading is low
