ok i took off my vacumm line that is underneath my swirl control valve and i am going to keep my scv on there but i want the butterfly out..and i know that when the engine is on the vacumm line sucks the shaft on the scv downwards and thats where i get confused..is that opening it or closing the butterflies???? this is the last thing i need to know before my swap so any info would be sweet thanks
