ok well i can only speak for myself but on my starion motor i converted the maf to a 1g maf and i ran a greddy type s with no issues with atmospheric blowoff, you just can't have the bov adjusted loose like a freakin skittle. also instead of just stepping on the clutch and letting the car roll, you have to let the car decelerate in gear until the rpm gets around 2k and then step on the clutch.
