Well my hks ssqv turned up the other day and am gonna fit it tomorrow but its come with the re-circulating adaptor too, so i have the choice either to have it vta or re-circulating. So its probably been asked before but i was wondering what is best either vta or re-circulating?
Mt cars a 03 wrx sti type uk, hasnt got anything done to it apart from a hks pannel filter.
thanks andy
