HKS in recirc mode

i currently have my HKS iin VTA mode and have noticed the odd idles and some running rick problems so i want to put it into recirculation mode. I still have the tip that replaces the fin and i think the factory hose. What else do i need before i go and replace things. Do i still run the small tube into the front part of the HKS? And also what does that little hose do? That is why i am looking for detailed pictures because it has been so long i want to make sure i still have all the parts.
 
running rick huh?
anyways. the little hose is the vacuum hose. need it if you have a boost guage. As for running VTA i used to get CEL with it and low idle and run rich . better now that i'm on recirc.
 
running it in recirc. is much better for the life of your turbo because it sends about 50% of the air back into the intake to the turbo and keeps it spinning during shifts - and it doesn't cause the car to run richer (which is also bad)- fitting the hks on the car's stock setup is tough though -you have to take off the front shield with the little allen nuts that run around the edges and put a recirc. fitting in the place of the little plastic fin - if you don't have one, pg has one that actually fits your recirc. tube about 1.25"- you prob have a snap ring that attaches your valve to your flange which is bolted to your cold pipe? you need to positions the bov so the recirc fitting is sitting at about 2 oclock compared to the factory bpv at about 4 - this way the vac line that attaches to the top of the valve will not hit the hood when you close it (if you upgrade to a fmic later this won't be an issue) - now the recirc. line attaches to the bottom of the valve - it still makes a cool noise just not as loud - running it like this will cause a tiny kink in the recirc hose but it will work just fine - there's not really a better solution unless you want to buy a super expensive no bend hose

You wanna know the solution to the kink? Get a different clamp for the recirc hose on the HKS and put the stock clamp over the kink. It will keep the hose rounded.

BTW your HKS is rubbing on the hood underpanels.
